“…The conjugated (sp 2 ) carbon lattice increases light absorption range thereby promoting charge separation. In allusion to this, various other composites of graphene and transition metal oxides resulted with improved photocatalytic activity are presented in Table 2 [210][211][212][213][214][215][216][217][218][219][220]. Besides graphene-based composites of mono transition metal oxides, their bimetallic composites have also been extensively explored with the benefits of visible light driven photocatalysis.…”

Transition metal oxides (TMO) and their carbon composites have become a glittering upcoming material science candidate. Their interesting properties, such as their meticulous morphology, plentiful availability, flexible surface chemistry along with outstanding mechanical, thermal, and optical properties make them ideal for efficient photocatalytic dye degradation. An extensive range of TMO, and their carbon composites are reviewed highlighting the progression and opportunities for the photocatalytic degradation of dyes. Here, we concisely describe the numerous techniques to extend the optical absorption of these TMOs involving dye sensitization, metal doping, etc. Besides this, an overview of all aspects of dye degradation along with the prevailing challenges for future utilization and development of such nanocomposites towards highly efficient dye degradation system are also reported.

Organic pollutants such as dyes, antibiotics, analgesics, herbicides, pesticides, and stimulants become major sources of water pollution. Several treatments such as absorptions, coagulation, filtration, and oxidations were introduced and experimentally carried out to overcome these problems. Nowadays, an advanced technique by photocatalytic degradation attracts the attention of most researchers due to its interesting and promising mechanism that allows spontaneous and non-spontaneous reactions as they utilized light energy to initiate the reaction. However, only a few numbers of photocatalysts reported were able to completely degrade organic pollutants. In the past decade, the number of preparation techniques of photocatalyst such as doping, morphology manipulation, metal loading, and coupling heterojunction were studied and tested. Thus, in this paper, we reviewed details on the fundamentals, common photocatalyst preparation for coupling heterojunction, morphological effect, and photocatalyst’s characterization techniques. The important variables such as catalyst dosage, pH, and initial concentration of sample pollution, irradiation time by light, temperature system, durability, and stability of the catalyst that potentially affect the efficiency of the process were also discussed. Overall, this paper offers an in-depth perspective of photocatalytic degradation of sample pollutions and its future direction.

“…Ilmenite (FeTiO 3 ) is one of the most studied earth-abundant minerals for various photocatalytic reactions [ [9] , [10] , [11] , [12] , [13] ]. Although ilmenite ore has been commonly used as a raw material to produce TiO 2 , several studies have demonstrated its photocatalytic activity to degrade different dyes, and its antibacterial activity has been recently revealed under light and dark conditions [ 12 , 13 ].…”
