Abstract

Significance This study analyzes the concept， scientific connotation， and current industrial applications of powder technology for carbon neutrality and evaluates its role in achieving global carbon neutrality goals.

Progress A systematic overview is provided of the applications of powder technology in energy conservation and emission reduction， carbon capture， utilization， and storage （CCUS）， and renewable energy utilization. The study summarizes its emission reduction effects in industries such as construction materials， chemicals， and energy， as well as its positive impact on environmental engineering， particularly in dust control and wastewater purification.

Conclusions and prospects Although powder technology has made certain progress in promoting energy conservation and emission reduction in industrial production， it still faces challenges in technological innovation， policy support， and market mechanisms. Future research should focus on developing more efficient and cost-effective powder technologies for carbon neutrality， strengthening international cooperation， improving market mechanisms， and raising public awareness to promote the application of powder technology in achieving carbon neutrality goals.The future development of carbon-neutral powder technologies should focus on the following key areas：

1）Technological Innovation： Continuous innovation in powder technologies is essential for developing more efficient and cost-effective energy-saving and emission-reduction methodologies. This includes the creation and implementation of advanced adsorbent materials and membrane separation techniques， which can significantly enhance energy utilization efficiency in industrial processes and reduce carbon emissions.

2）Policy Support： Strengthening government policy support for carbon-neutral powder technologies is crucial. This can be achieved through the provision of fiscal subsidies， tax incentives， and green financial mechanisms to incentivize enterprises to invest in and adopt low-carbon technologies.

3）Market Mechanism： Establishing a robust carbon emission rights trading market and implementing a rational carbon pricing mechanism is essential for facilitating the market-oriented application of carbon-neutral powder technologies.

4）International Cooperation： Enhancing international technical exchanges and cooperation is vital for sharing successful experiences and technologies， thereby promoting global efforts toward carbon reduction.

5）Public Participation： Increasing public awareness of carbon neutrality and encouraging participation from all sectors of society in carbon reduction actions can foster a collaborative societal atmosphere dedicated to achieving global carbon neutrality.

6）Interdisciplinary Research： Promoting interdisciplinary integration of powder technologies with environmental science， energy science， and other fields is essential for conducting cross-disciplinary research. This approach can generate innovative ideas and comprehensive solutions to support carbon neutrality initiatives.
