Description
Benteng Song, Zhonghan Feng, Xin-Ping Wu, and a wider team wrote this chemistry paper, published in 2025. It finds a new way that zinc oxide, a workhorse industrial catalyst, gains the active hydrogen pairs it needs to turn carbon dioxide into methanol.
The active pairs, hydrogen atoms bridging two zinc atoms, were thought to form only when hydrogen gas splits on the surface. Using magnetic resonance methods, the team showed the pairs can also form when surface hydroxyl groups drift over to nearby oxygen gaps. Heat tests mapped the steps: at low heat the pairs stay idle, at mid heat they convert an intermediate, and at higher heat methanol forms and leaves. The finding reveals a built-in source of active hydrogen that needs no hydrogen gas feed.
