“…Semiconductor photocatalysis is an important option for solar energy conversion and pollutant degradation according to the idea of green chemistry. For purposes of degradation of the pollutants, a known set of catalysts is already designed [16]: double layered hydroxides [17], titanium dioxide [18], composites based on TiO2 [19], other oxides (ZnO [20], WO3 [21]), composites with oxides [22-24, 25, 26], as well as composites with MoS2 [27][28][29].…”

Zirconium trisulfide ZrS3 is a representative of transition metal polysulfides containing sulfur as S -1 in polysulfide, usually disulfide S2 2groups. Semiconductive zirconium trisulfide which absorbs visible light near UV edge was considered as a possible photocatalyst. We experimentally studied photodecoloration of methyl orange in presence of ZrS3. It was shown for the first time that crystalline ZrS3 strongly deepens photodegradation reaction, and in one case the methylene orange conversion reached almost 100%. The rates of degradation curves were associated with the ZrS3 samples morphology; the best result revealed for microribbons ZrS3 synthesized at 650°C.

The search for greener alternatives to perform organic reactions has become the order of the day in the chemistry community. In this regard, the use of heterogeneous photocatalysts has emerged as a powerful alternative to replace transition metal-based complexes and organic dyes to enable light-driven organic transformations. Within this realm, metal oxide semiconductors (MOS) have become increasingly popular due to their recyclability, availability, energy efficiency, photo-and chemical stability and generally low toxicity. Here, we cover the most relevant literature related to the use of MOS as photocatalysts to light induce organic reactions, including oxidations, C-C and C-heteroatom bond formations. We also discuss the mechanisms involved in these processes, as well as the hitherto best known MOS modifications able to enhance their photocatalytic performance.

Highly active photocatalysts driving chemical reactions are of paramount importance toward renewable energy substitutes and environmental protection. As a fascinating Aurivillius phase material, Bi 2 MoO 6 has been the hotspot in photocatalytic applications due to its visible light absorption, nontoxicity, low cost, and high chemical durability. However, pure Bi 2 MoO 6 suffers from low efficiency in separating photogenerated carriers, small surface area, and poor quantum yield, resulting in low photocatalytic activity. Various strategies, such as morphology control, doping/defect-introduction, metal deposition, semiconductor combination, and surface modification with conjugative π structures, have been systematically explored to improve the photocatalytic activity of Bi 2 MoO 6 . To accelerate further developments of Bi 2 MoO 6 in the field of photocatalysis, this comprehensive Review endeavors to summarize recent research progress for the construction of highly efficient Bi 2 MoO 6 -based photocatalysts. Furthermore, benefiting from the enhanced photo catalytic activity of Bi 2 MoO 6 -based materials, various photocatalytic applications including water splitting, pollutant removal, and disinfection of bacteria, were introduced and critically reviewed. Finally, the current challenges and prospects of Bi 2 MoO 6 are pointed out. This comprehensive Review is expected to consolidate the existing fundamental theories of photo catalysis and pave a novel avenue to rationally design highly efficient Bi 2 MoO 6 -based photocatalysts for environmental pollution control and green energy development.
