Precipitation synthesis and characterization of SnO<sub>2</sub>@g-C<sub>3</sub>N<sub>4</sub> heterojunctions for enhanced photocatalytic H<sub>2</sub> production.
Ontology highlight
ABSTRACT: This study reports the development of SnO2@g-C3N4 heterojunctions, a hybrid semiconductor photocatalyst with varying mass percent ratios using a facile precipitation method for hydrogen (H2) production. The synergistic effect between the SnO2 nanoparticles and g-C3N4 sheets suppresses the charge recombination and enhances carrier separation, leading to improved photocatalytic activity. The nanocomposites demonstrate increased hydrogen production across all composites, with SC-20 sample (i.e., 80% SnO2 and 20% g-C3N4) achieving the highest H2 production rate of 287.7 μmol g-1 h-1, that is, 1.87-fold and 1.63-fold higher than that of SnO2<
