“…Notably, the Au@CdS (core@shell)-assembled g-C 3 N 4 nanosheet shows ∼126-folds (0.15 vs 19 μmol/h/g) higher H 2 -production rate than bare g-C 3 N 4 due to enhanced light absorption and Z-scheme separation of charge-carriers . Other Z-scheme systems showing excellent photocatalytic H 2 O splitting efficiency and high stability and selectivity include g-C 3 N 4 –Ag 3 PO 4 –Ag 2 MoO 4 , g-C 3 N 4 –Au-TiO 2 , g-C 3 N 4 –TiO 2 , and g-C 3 N 4 –NiTiO 3 (SI Table S4).…”

Nanotechnology has unprecedentedly revolutionized human societies over the past decades and will continue to advance our broad societal goals in the coming decades. The research, development, and particularly the application of engineered nanomaterials have shifted the focus from "less efficient" single-component nanomaterials toward "superior-performance", nextgeneration multifunctional nanohybrids. Carbon nanomaterials (e.g., carbon nanotubes, graphene family nanomaterials, carbon dots, and graphitic carbon nitride) and metal/metal oxide nanoparticles (e.g., Ag, Au, CdS, Cu2O, MoS2, TiO2, and ZnO) combinations are the most commonly pursued nanohybrids (carbon-metal nanohybrids; CMNHs), which exhibit appealing properties and promising multifunctionalities for addressing multiple complex challenges faced by humanity at the critical energy-water-environment (EWE) nexus. In this frontier review, we first highlight the altered and newly emerging properties (e.g., electronic and optical attributes, particle size, shape, morphology, crystallinity, dimensionality, carbon/metal ratio, and hybridization mode) of CMNHs that are distinct from those of their parent component materials. We then illustrate how these important newly emerging properties and functions of CMNHs direct their performances at the EWE nexus including energy harvesting (e.g., H2O splitting and CO2 conversion), water treatment (e.g., contaminant removal and membrane technology), and environmental sensing and

“…For example, Li et al cleverly coated the surface of the NiTiO 3 fiber with sheet-like Bi 2 MoO 6 and built a heterojunction to eliminate tetracycline hydrochloride in the water. Kim et al published a report on an Ag-assisted NiTiO 3 /g-C 3 N 4 composite catalyst to increase hydrogen evolution rate. Unfortunately, NiTiO 3 has the disadvantages of high electron–hole recombination rate and low adsorption capacity due to the narrow band gap. , …”

As the demand of fossil fuels continues to expand, hydrogen energy is considered a promising alternative energy. In this work, the NiTiO 3 −CuI-GD ternary system was successfully constructed based on morphology modulation and energy band structure design. First, the one-pot method was used to cleverly embed the cubes CuI in the stacked graphdiyne (GD) to prepare the hybrid CuI-GD, and CuI-GD was anchored on the surface of NiTiO 3 by simple physical stirring. The unique spatial arrangement of the composite catalyst was utilized to improve the hydrogen production activity under light. Second, to combine various characterization tools and energy band structures, we proposed an step-scheme (S-scheme) heterojunction photocatalytic reaction mechanism, among them, the tubular NiTiO 3 formed by the selfassembled of nanoparticles provided sufficient sites for the anchoring of CuI-GD, and the thin layer GD acted as an electron acceptor to capture a large number of electrons with the help of the conjugated carbon network; cubes CuI could consume holes in the reaction system; the loading of CuI-GD greatly improved the oxidation and reduction ability of the whole catalytic system. The S-scheme heterojunction accelerated the transfer of carriers and improved the separation efficiency. The experiment provides a new insight into the construction of an efficient and eco-friendly multicatalytic system.

“…In addition to these, BaTiO 3 based photocatalysts are also reported for photocatalytic organic pollutant degradation − and H 2 evolution. − Several other photocatalysts based on titanate perovskites such as MgTiO 3 , − PbTiO 3 , , NiTiO 3 , , ZnTiO 3 , and FeTiO 3 are also reported for photocatalytic degradation of different organic pollutants. MgTiO 3 and NiTiO 3 based photocatalysts are also reported for the photocatalytic H 2 evolution reaction. − For example, Wu et al have reported the synthesis of a ternary BaTiO 3 /Au/gC 3 N 4 heterojunction photocatalyst, wherein Au acts as an electron mediator in the involved Z-scheme mechanism . This photocatalyst showed almost complete degradation of RhB (20 min) in comparison to the bare components and binary BaTiO 3 /gC 3 N 4 heterojunction, under simulated sunlight irradiations.…”

The use of solar energy to catalyze the photo-driven processes has attracted tremendous attention from the scientific community because of its great potential to address energy and environmental issues. In this regard, several attempts have been made by researchers to design and develop different materials with enhanced photocatalytic efficiencies. This Review comprehensively summarizes the recent reports on perovskite oxide based photocatalysts for organic pollutant degradation, water splitting, carbon dioxide conversion, and nitrogen fixation along with the basic understanding of involved mechanisms, current trends and advances in the field. The different design, synthesis, and development strategies have been discussed in detail to provide a comprehensive view of materials’ fabrication that influences their photocatalytic properties. Subsequently, the insights from recent reports on different perovskite oxide based materials, including simple oxides, mixed oxides, and layered perovskite oxides, are provided for the above-mentioned photocatalytic applications in a detailed manner. Finally, a summary of photocatalytic applications and a perspective on future research direction have been discussed. Based on the research progress in this field, it is highly anticipated that the photocatalytic systems, comprising perovskite oxide materials along with groundbreaking technologies for large-scale realization of these processes, can be established in the near future to address the energy and environment-oriented challenges.
