Bio‐Inspired Carbon Spheres Enable Active Sites Multiscale‐Anchoring and Pre‐Reduction
Carbon Energy, EarlyView.Combining the wet‐spinning technique with a “bionic design” concept, a bio‐inspired carbon sphere support with internal finger‐shaped pores and external craquelure structures is designed and constructed, and the corresponding carbon sphere reactor is fabricated through the multiscale anchoring and the pre‐reduced promoting, and verified for application

A Self‐Sustained System for Producing Green Hydrogen via Moisture Power
Carbon Energy, EarlyView.A multifunctional PAM‐PSSA‐MgCl2 gel enables a self‐powered Moisture‐Electricity‐Water‐Hydrogen system that harvests atmospheric water, generates electricity via moisture‐driven processes, and directly electrolyzes the collected water for hydrogen production. The material delivers 1.87 V, 450 μA cm−2 (MEG), and 1.318 g g−1 (AWH) water uptake, achieving

Chemie Ingenieur Technik, EarlyView.The steel industry accounts for about 7%‐9% of global CO2 emissions. While H2‐based direct reduction is a long‐term route, near‐term solutions are needed for existing plants. Internal carbon cycles reuse steelworks off‐gases and by‐products, enabling circular carbon use and supporting CCU integration.
