There is no doubt that the rate of hydrogen production via the water splitting reaction is profoundly affected to a remarkable degree based on the isolation of photogenerated electrons from holes. The precipitation of any cocatalysts on the substrate surfaces (including semiconductor materials) provides significant hindrance to such reincorporation. In this regard, a graphite-like structure in the form of mesoporous g-C 3 N 4 formed in the presence of a template of mesoporous silica has been synthesized via the known combustion method. Hence, the resulting g-C 3 N 4 nanosheets were decorated with varying amounts of mesoporous CoAl 2 O 4 nanoparticles (1.0-4.0%). The efficiencies of the photocatalytic H 2 production by CoAl 2 O 4 -doped g-C 3 N 4 nanocomposites were studied and compared with those of pure CoAl 2 O 4 and g-C 3 N 4 . Visible light irradiation was carried out in the presence of glycerol as a scavenger. The results showed that the noticeable photocatalytic enhancement rate was due to the presence of CoAl 2 O 4 nanoparticles distributed on the g-C 3 N 4 surface. The 3.0% CoAl 2 O 4 -g-C 3 N 4 nanocomposite had the optimum concentration. This photocatalyst showed extremely high photocatalytic activities that were up to 22 and 45 times greater than those of CoAl 2 O 4 and g-C 3 N 4 , respectively. This photocatalyst also showed 5 times higher photocatalytic stability than that of CoAl 2 O 4 or g-C 3 N 4 . The presence of CoAl 2 O 4 nanoparticles as a cocatalyst increased both the efficiency and productivity of the CoAl 2 O 4 -g-C 3 N 4 photocatalyst. This outcome was attributed to the mesostructures being efficient charge separation carriers with narrow band gaps and high surface areas, which were due to the presence of CoAl 2 O 4 .
