“…Besides, the high S BET not only promotes the adsorption efficiency of pollutants, CO 2 , and water molecules but also swiftly activates the catalyst for redox reactions at the interface. 43 N 2 adsorption–desorption isotherms were produced to calculate the S BET value of the as-fabricated ZnO, CdS, ZnO 0.5 CdS 0.5 , and ZnO 0.45 Cu 0.1 CdS 0.45 catalysts (Fig. 7).…”

“…But usually, the activity of these sensing materials generally decreases by template methods, along with the demerits of complicated synthetic procedures and high manufacturing costs, which may give them a setback or keep them on hold to use them in a variety of applications. To overcome these disadvantages, different nanostructures and microstructures of varying chemical compositions have been developed by several chemical routes for functional properties and applications. − …”

CeO 2 and ZrO 2 nanospheres were successfully prepared by hydrothermal synthesis. From the as-synthesized pristine nanostructures, ZrO 2 −CeO 2 nanocomposite heterostructures with different weight percent ratios of 2.5, 5, 7.5, and 10% were prepared mechanically. The morphology and structural characteristics of the as-synthesized metal oxides and nanocomposites were investigated by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy studies. The UV−visible diffuse reflectance spectroscopic technique revealed band gaps of 2.95, 2.96, 2.91, and 2.83 eV of the 2.5− 10% ZrO 2 −CeO 2 composite heterostructures, respectively, which were found to be smaller than that of pristine CeO 2 (3.03 eV). Furthermore, the Brunauer−Emmett−Teller surface area studies revealed enhanced surface areas of 81.5, 67.6, 74.8, and 58.4 m 2 /g for 2.5−10% ZrO 2 −CeO 2 nanocomposite heterostructures, respectively, as compared to the pure CeO 2 having 53.2 m 2 /g. 7.5% ZrO 2 -decorated CeO 2 nanocomposite heterostructure manifested remarkable enhancement in the sensing performance response of 1475 displayed as compared to the pure CeO 2 response of 205. The improved sensing performance of the 7.5% ZrO 2 −CeO 2 sensor is likely to have originated from the decrease in the band gap, enhanced surface area, the existence of large oxygen vacancies on the ZrO 2 surface, and the formation of ZrO 2 −CeO 2 heterojunctions in nanocomposites. Further, the enhanced gas sensing properties along with the sensing mechanism are discussed in detail.

“…Their transformation to H 2 has been reported to be an ideal solution to reduce fossil fuel use and the environmental problems related to fossil fuels [47]. The PWS process is considered to be the most efficient and renewable option for H 2 generation [47][48][49][50]. In this process, reductive and oxidative reactions take place simultaneously under solar light illumination [51].…”

The global climate crisis has cultivated the demand for sustainable energy resources as fossil derivative fuels are functional in catalyzing the rate of environmental breakdown. Sustainable energy solutions generate various renewable energy prospects capable of delivering efficient energy operations. Among these prospects, green H2 energy generated via overall water splitting is an effective approach towards sustainability ascribed to the higher gravimetric density and efficiency of H2 fuel. In this review, we sought to discuss the applicability and challenges of graphene-based derivatives in H2 evolution operations through photochemical, electrochemical and photoelectrochemical water-splitting pathways. The unique layered structure of graphene-based derivatives alongside marvelous optoelectronic and physicochemical properties ease out the thermodynamic uphill of water splitting better than their non-layered counterparts. In addition, the heterojunction formation in the graphene derivatives with visible light catalysts propels the kinetics of HER. Functionalized GO and rGO derivatives of graphene are riveting catalysts that have received extensive interest from researchers attributed to their accelerated chemical and mechanical stability, tunable band structure and larger surface area, providing more exposed active sites for HER. The surface organic functional groups of GO/rGO assist in establishing synergetic interfacial contact with other catalysts. Thus, these groups provide structural and chemical versatility to GO/rGO-based heterostructured catalysts, which effectively improve their physicochemical parameters that drive their catalytic performance towards HER. In order to develop a cost-effective and highly efficient catalytic system, graphene-based derivatives are promising heterostructured catalysts that exhibit a good relationship between catalytic efficiency and robustness.
