Oxygen-deficient MoO₃₋ₓ evoked synergistic photo-thermal catalytic CO₂ reduction over g-C₃N₄

Developing inexpensive co-catalysts for photo-thermal synergistic catalysis by artificially inducing active sites on non-noble metal compounds has drawn much attention recently. In this work, oxygen-deficient molybdenum oxide (MoO3−x) was in situ photodeposited on the surface of graphite-like carbon...
