Abstract Rational design of low‐cost and efficient transition‐metal catalysts for low‐temperature CO 2 activation is significant poses great challenges. Herein, a strategy via regulating the local electron density active sites developed to boost methanation that normally requires >350 °C commercial Ni catalysts. An optimal Ni/ZrO catalyst affords an excellent performance hitherto, with conversion 84.0 %, CH 4 selectivity 98.6 % even at 230 GHSV 12,000 mL g −1 h 106 h, reflecting one best...
Abstract CO 2 hydrogenation to chemicals and fuels is a significant approach for achieving carbon neutrality. It essential rationally design the chemical structure catalytic active sites towards development of efficient catalysts. Here we show Ce-CuZn catalyst with enriched Cu/Zn-O V -Ce fabricated through atomic-level substitution Cu Zn into Ce-MOF precursor. The exhibits high methanol selectivity 71.1% space-time yield up 400.3 g·kg cat −1 ·h excellent stability 170 h at 260 °C, comparable...

Hydrous hydrazine (N2H4·H2O) has great potential as a convenient and safe hydrogen source for fuel cells. Tremendous efforts have been made to develop economic efficient metal catalysts evolution from N2H4·H2O, but it remains huge challenge. Herein, the first time, noble-metal-free CuNi nanoparticles (NPs) immobilized on lanthanum oxycarbonate/reduced graphene oxide nanocomposites (CuNi/La2O2CO3/rGO) were successfully fabricated through an impregnation-reduction approach. Well-dispersed...
Reconstruction of heterogeneous catalyst is essential for understanding the structure-performance relationship, however, it still remains limitations methodology development. Herein we reveal a gas induced activation strategy to reconstruct surface CuZnO x /mSi through pretreating in various environments, including CO, H2, and H2&CO mixture. Specifically, high resolution scanning transmission electron microscopy as well elemental distribution analysis disclosed that H2 pretreatment...
