Anti‐Stoke effect induced enhanced photocatalytic hydrogen production

Photocatalytic hydrogen production via solar energy is considered one of the most strategic ways to produce renewable energy. However, expensive Pt normally used as cocatalyst during photocatalysis, which prevents commercialization. Therefore, extensive research has been performed seek abundant and low-cost alternative catalysts. In this work, MoS2 quantum dots (QDs) synthesized by a hydrothermal method are incorporated with graphitic carbon nitride form heterostructure for photocatalytic evolution. QDs/g-C3N4 containing 5% 10% QDs exhibited high 140 152 µmol h−1g−1, respectively, demonstrating potential an effective economic cocatalyst. Detailed investigations indicate that incorporating reduces bandgap, suppresses recombination, enhances electron kinetic resulting from anti-Stoke effect, thus leading better performance
