Abstract
Significance Particle preparation and processing technologies provide fundamental scientific and engineering foundations for the development of advanced materials， high-end manufacturing， energy transformation， environmental protection， and emerging strategic industries. The properties and functions of particles are strongly determined by their size distribution， morphology， surface structure， composition， internal architecture， and interfacial characteristics. Therefore， precise regulation of particle formation， growth， assembly， separation， and processing behaviors has become a critical scientific challenge for achieving high-performance materials and efficient industrial processes. Over the past decade， driven by major demands in industrial upgrading， energy transition， environmental sustainability， and intelligent manufacturing， particle preparation and processing technologies in China have experienced rapid development and achieved significant technological breakthroughs. This review systematically summarizes recent advances in particle preparation and processing in China over the past decade， with a focus on advanced preparation strategies， surface and interface engineering， functional particle development， process intensification， intelligent technologies， and industrial applications. The key scientific challenges and technical limitations are analyzed， and future development directions are proposed to provide guidance for disciplinary innovation and technological advancement in related fields.
Progress In recent years， particle preparation and processing technologies in China have undergone a transition from conventional manufacturing approaches toward precision control， multifunctional integration， green production， and intelligent regulation. Advanced preparation technologies have increasingly emphasized the controllable synthesis of particles with precisely tailored size， morphology， composition， hierarchical structures， and surface properties. Significant progress has been achieved in various particle manufacturing strategies， including bottom-up synthesis， top-down processing， self-assembly， template-assisted preparation， and continuous manufacturing technologies. These advances have enabled the fabrication of advanced particles with improved catalytic activity， energy-storage capability， separation performance， and functional properties. Surface engineering and interfacial regulation have become important approaches for improving particle performance. Through surface modification， heterostructure construction， defect engineering， interface optimization， and functional coating， researchers have achieved effective regulation of surface chemistry， charge transfer behavior， adsorption properties， and reaction kinetics. These advances have promoted the rapid development of functional particles， including catalytic particles， energy-storage materials， electronic materials， and advanced energy-related particles. In particular， catalytic particles and electrocatalytic materials have provided essential support for hydrogen energy utilization， carbon dioxide conversion， environmental catalysis， and sustainable chemical processes. Meanwhile， energy-storage particles， including electrode materials and functional additives， have contributed to advances in lithium-ion batteries， emerging battery technologies， and energy conversion systems. Beyond functional materials， particle processing technologies associated with resource utilization and industrial manufacturing have also progressed significantly. Mineral processing， particle separation， multiphase-flow regulation， and process intensification technologies have continuously developed toward higher efficiency， lower energy consumption， and improved resource utilization. Advanced separation methods， optimized multiphase transport processes， and intensified reaction systems have enhanced the efficiency of industrial particle processing and promoted the sustainable utilization of natural resources and industrial waste. Meanwhile， the integration of advanced characterization techniques and digital technologies has accelerated the transformation of particle science toward intelligent manufacturing. In situ characterization methods， online monitoring technologies， intelligent sensing systems， and computational modeling approaches have provided new opportunities for understanding particle formation mechanisms and controlling particle processing behaviors in real time. The combination of experimental characterization， theoretical simulation， and data-driven methods has enabled deeper insights into particle evolution processes， interfacial interactions， and structure–property relationships. Furthermore， digital design strategies and intelligent control technologies have gradually extended from laboratory-scale research to industrial applications， enabling precise regulation throughout the entire particle preparation and processing chain.Despite these achievements， several scientific and technological challenges remain. The complex mechanisms governing particle nucleation， growth， aggregation， surface evolution， and interface formation are still not fully understood， particularly under dynamic and industrial-scale conditions. Achieving simultaneous control of particle structure， functionality， production efficiency， and environmental sustainability remains challenging. In addition， the scale-up of advanced particle preparation technologies， standardization of evaluation methods， and development of high-performance processing equipment require further investigation.
Conclusions and Prospects Particle preparation and processing technologies in China are currently undergoing rapid transformation toward precision preparation， interfacial regulation， functional integration， green and low-carbon manufacturing， and intelligent technologies. Multidisciplinary integration has become a major driving force for innovation， connecting particle science with chemistry， materials science， engineering， information technology， energy science， environmental science， and biomedical fields. Future development should focus on establishing intelligent and integrated particle manufacturing systems through the deep integration of artificial intelligence， digital twins， high-throughput computing， machine learning， and advanced characterization technologies. These emerging approaches are expected to enable intelligent optimization throughout the entire lifecycle of particles， including molecular-level design， controllable synthesis， processing regulation， performance evaluation， and application deployment. Meanwhile， further efforts are required to establish comprehensive standards， databases， and evaluation systems for particle preparation and processing， thereby enabling reliable comparison and industrial translation of emerging technologies. The independent innovation capability of key preparation equipment and large-scale processing technologies should also be strengthened to support high-end manufacturing. Moreover， interdisciplinary collaboration between particle science and strategic emerging fields， including renewable energy， environmental remediation， biomedicine， aerospace engineering， and advanced manufacturing， should be continuously promoted. Through these efforts， particle preparation and processing technologies are expected to achieve higher levels of precision， sustainability， intelligentization， and industrial applicability， providing critical technological support for future industries and national strategic development.
