Abstract Hydrogen peroxide (H2O2) is not only a key eco-friendly oxidizer but also a promising energy carrier with an energy density comparable to that of compressed hydrogen. The industrial production of H2O2 relies on the energy-intensive... Read More
Abstract The photoelectrochemical nitrate reduction reaction (PEC NO3RR) potentially converts nitrate, a major water pollutant, into NH3, which is an eco-friendly, next-generation energy source. However, achieving high efficiency in the PEC... Read More
Abstract To commercialize the technology of photoelectrochemical hydrogen production, it is essential to surpass the US. Department of Energy target of 0.36 mmol h−1 cm−2 for 1-sun hydrogen production rate. In this study, we utilize crystal... Read More
Abstract For practical photoelectrochemical water splitting to become a reality, highly efficient, stable and scalable photoelectrodes are essential. However, meeting these requirements simultaneously is a difficult task, as improvements in... Read More
Abstract Tin–lead halide perovskites (TLHPs) are promising photoactive materials for photovoltaics (PVs) due to reduced toxicity and broad light absorption. However, their inherent ionic vacancies facilitate inward metal diffusion, accelera... Read More
Summary Small-area photoelectrodes are used to study fundamental science and material development for photoelectrochemical (PEC) water splitting cells at the laboratory scale. For practical applications, however, one needs to develop scalab... Read More
