The synergy of in situ-generated Ni⁰ and Ni₂P to enhance CO adsorption and protonation for selective CH₄ production from photocatalytic CO₂ reduction

Abstract

The synergy between in situ-generated Ni0 sites and Ni2P selectively boosts CH4 formation by enhancing *CO adsorption and protonation.

In situ formed nickel phosphide/iron oxide heterojunction for accelerating hydrogen generation

“…Fig. 2d exhibits distinct lattice fringes with a spacing of approximately 0.221 nm, which matches well with the Ni 2 P (111) plane, 35 and a spacing of about 0.543 nm corresponding to the Fe 3 O 4 (111) plane. 36 This arrangement also appears in the TEM and HRTEM images of Fe 3 O 4 –Ni 2 P@C-600 (Fig.…”

“…03-0953). 35,37 The peaks at 30.0, 35.3, 43.0, 56.9, and 62.4° correspond to inverse spinel Fe 3 O 4 (220), (311), (400), (511), and (440) planes [PDF no. 89-3854], 36 and the peaks at 37.2, 43.1, and 62.9° match well with the NiO (111), (200), and (220) planes (PDF no.…”

Effects of N,S doping on a graphene oxide aerogel for adsorption and photocatalytic reduction of carbon dioxide

“…11–14 Considered as artificial photosynthesis, photocatalytic CO 2 reduction is an effective strategy for solving the global warming and energy crisis caused by the increase in the use of fossil fuels and the emission of CO 2 , and is of great significance for achieving sustainable development. 15,16…”
