“…Because of the short distance between the conduction band (CB) of Bi 2 O 3 and the valence band (VB), graphene can be designed for the sharing of Bi 2 O 3 and graphene [85]. Under such conditions, electrons generated in the CB of Bi 2 O 3 would quickly be coupled with graphene VB holes [86]. Therefore, the photogenerated electrons accumulated on the CB of graphene display strong reduction ability, and the photogenerated holes on the VB of Bi 2 O 3, exhibit excellent oxidation ability [87,88].…”

Photocatalysis is a classical solution to energy conversion and environmental pollution control problems. In photocatalysis, the development and exploration of new visible light catalysts and their synthesis and modification strategies are crucial. It is also essential to understand the mechanism of these reactions in the various reaction media. Recently, bismuth and graphene’s unique geometrical and electronic properties have attracted considerable attention in photocatalysis. This review summarizes bismuth-graphene nanohybrids’ synthetic processes with various design considerations, fundamental mechanisms of action, heterogeneous photocatalysis, benefits, and challenges. Some key applications in energy conversion and environmental pollution control are discussed, such as CO2 reduction, water splitting, pollutant degradation, disinfection, and organic transformations. The detailed perspective of bismuth-graphene nanohybrids’ applications in various research fields presented herein should be of equal interest to academic and industrial scientists.

LaFeO3/Diatomite porous disk composites have been successfully prepared by sol‐gel method for the photocatalytic oxidative degradation of ciprofloxacin (CIP) compounds. The structure of the porous disc plays an important role in improving the photocatalytic activity by increasing the contact area between the photocatalyst and CIP to enhance CIP molecule adsorption. Meanwhile, the porous disk composite photocatalysts can effectively prevent the recombination of light‐induced electron‐hole pairs. A photo‐Fenton‐like reaction is triggered by addition of H2O2, which further remarkably improves the photocatalytic activity of LaFeO3/Diatomite. Then, the factors like catalyst concentration, H2O2 dosage, initial pH and CIP concentration of the solution responsible for the enhanced photocatalytic performance of the reaction system are investigated. The optimal degradation rate of ciprofloxacin by the LaFeO3/Diatomite catalyst is 99.02 % after visible light irradiation for 150 min, which is 1.22 times of the pure LaFeO3. The catalysts have a much high stability which can be recycled for many times and the degradation rate of four cycles is still about 98 %. The excellent performance and high photocatalytic efficiency of the LaFeO3/Diatomite photocatalyst make it have potential application foreground in the treatment of pharmaceutical wastewater.
