“…The series resistance (R s ) indexed to the conductivity of the electrode can be estimated using the interception in the x-axis, and the charge-transfer resistance (R ct ) at the interface between the electrolyte and the BiVO 4 nanostructure can be estimated by observing the semicircle at the high frequency region. 35,36 The R s values of around 50 to 70 U were obtained for all the samples.…”

“…The first applications of Sb 2 S 3 involved forming a heterojunction with other materials such as NiO, , TiO 2 , − BiVO 4 , WO 3 , − ZnO, , Fe 2 O 3 , CuInS 2 , and Sb 2 O 3 . , In these cases, Sb 2 S 3 mostly functions to increase the photoanode light absorption edge and introduce a visible light response due to the high band gap of photoanode materials such as TiO 2 and WO 3 . The first application of Sb 2 S 3 as a standalone photoanode material was reported by DeAngelis et al where a photocurrent of 0.6 mA cm –2 was achieved at 1 V RHE without any additional overlayers .…”

Chalcogenide semiconductors offer excellent optoelectronic properties for their use in solar cells, exemplified by the commercialization of Cu(In,Ga)Se 2 -and CdTe-based photovoltaic technologies. Recently, several other chalcogenides have emerged as promising photoabsorbers for energy harvesting through the conversion of solar energy to electricity and fuels. The goal of this review is to summarize the development of emerging binary

“…Finally, rGO has been found to significantly improve the charge-separation and -transport properties when deposited at the interface of a type II junction. , Moreover, although it does not contribute much to light absorption itself, the incorporation of rGO provides a good basis for the overgrowth of the photosensitizer. An increased contribution to light harvesting (in the visible and infrared regions) has been found in nanostructured eRGO/NiO/Fe 2 O 3 photoanodes .…”

Noble-Metal-Free Multicomponent Nanointegration for Sustainable Energy Conversion

Global energy and environmental crises are among the most pressing challenges facing humankind. To overcome these challenges, recent years have seen an upsurge of interest in the development and production of renewable chemical fuels as alternatives to the nonrenewable and high-polluting fossil fuels. Photocatalysis, photoelectrocatalysis, and electrocatalysis provide promising avenues for sustainable energy conversion. Single-and dual-component catalytic systems based on nanomaterials have been intensively studied for decades, but their intrinsic weaknesses hamper their practical applications. Multicomponent nanomaterial-based systems, consisting of three or more components with at least one component in the nanoscale, have recently emerged. The multiple components are integrated together to create synergistic effects and hence overcome the limitation for outperformance. Such higher-efficiency systems based on nanomaterials will potentially bring an additional benefit in balance-of-system costs if they exclude the use of noble metals, considering the expense and sustainability. It is therefore timely to review the research in this field, providing guidance in the development of noble-metal-free multicomponent nanointegration for sustainable energy conversion. In this work, we first recall the fundamentals of catalysis by nanomaterials, multicomponent nanointegration, and reactor configuration for water splitting, CO 2 reduction, and N 2 reduction. We then systematically review and discuss recent advances in multicomponent-based photocatalytic, photoelectrochemical, and electrochemical systems based on nanomaterials. On the basis of these systems, we further laterally evaluate different multicomponent integration strategies and highlight their impacts on catalytic activity, performance stability, and product selectivity. Finally, we provide conclusions and future prospects for multicomponent nanointegration. This work offers comprehensive insights into the development of cost-competitive multicomponent nanomaterial-based systems for sustainable energy-conversion technologies and assists researchers working toward addressing the global challenges in energy and the environment.
