中国研究人员开发了一种受光合作用启发的太阳能驱动过程，将二氧化碳和水转化为用于汽油生产的化学物质。这种方法使用一种新型材料存储电能，以高效驱动化学反应。这一突破可能为航空和航运等部门提供燃料。
中国科学家开发了一种仿生方法，利用太阳能将二氧化碳和水转化为有价值的化学物质，例如汽油的构建块。该团队来自中国科学院和香港科技大学，他们表示已开发出一种能够存储少量电能的材料，以帮助高效驱动化学反应。
当与催化剂配对时，该材料可将二氧化碳转化为各种化学物质，从而实现太阳能驱动的生产碳 monoxide。这种碳 monoxide 可以进一步转化为燃料，为航空和航运等难以电气化的部门提供可能的替代方案。
团队在同行评审期刊《Nature Communications》上发表的论文中写道：“这项工作建立了生物启发式电荷库策略，用于高效二氧化碳光还原，提供了一种通用的太阳能燃料生产方法。”该论文于上周发表。
这一创新模仿植物的光合作用，利用太阳能直接产生燃料，可能有助于减少对化石燃料的依赖。该研究强调了太阳能能源在可持续化学中的潜力。
Researchers have invented a new electrode that captures carbon dioxide from exhaust gases and converts it into formic acid in a single step. This device operates effectively with unpurified gases, including those at atmospheric levels, offering a practical approach to reducing pollution. The breakthrough, detailed in ACS Energy Letters, outperforms existing technologies under realistic conditions.

Researchers at the University of Santiago de Compostela report a light-driven method that directly “allylates” methane—adding an allyl group that can be used to build more complex molecules—and they demonstrate the approach by producing the nonsteroidal estrogen dimestrol from methane.
General Galactic, a startup cofounded by a former SpaceX engineer, is preparing to test a water-based propellant this fall. Success could enable deeper space exploration by producing fuel from local resources. The concept builds on long-standing assumptions about using lunar and Martian ice for propulsion.

Researchers propose using two resilient Earth microbes to create concrete-like structures from Martian regolith, potentially aiding human settlements on the Red Planet. This approach leverages biomineralization to produce building materials and oxygen on-site. The method draws from natural processes and aims to support sustainable habitats through in situ resource utilization.
