Straightforward electrochemical synthesis of a CoO nanopetal/ZnO nanoplate p-n junction for photoelectrochemical water splitting.

Hydrogen production through photoelectrochemical (PEC) reactions is an innovative and promising approach to producing clean energy. The PEC working electrode of a CoO/ZnO-based p-n heterojunction was prepared by a straightforward electrochemical deposition with different deposition times onto an FTO (Fluorine-doped Tin Oxide) glass substrate. The successful synthesis of the materials was confirmed through analysis using XRD, FTIR, SEM-EDX, DRS, and PL techniques.

Influence of thickness and morphology of MoS on the performance of counter electrodes in dye-sensitized solar cells.

Non-platinum electrodes for photoelectric devices are challenging and attractive to the scientific community. A thin film of molybdenum disulfide (MoS) was prepared on substrates coated with fluorine-doped tin oxide (FTO) to substitute the platinum counter electrode (CE) for dye-sensitized solar cells (DSSCs). Herein, we synthesized layered and honeycomb-like MoS thin films via the cyclic voltammetry (CV) route.

Enhancing Green Product Generation of Photocatalytic NO Oxidation: A Case of WO Nanoplate/g-CN S-Scheme Heterojunction.

Nitric oxide (NO) removal by photocatalytic oxidation over g-CN has achieved more efficient results. However, there is a concern about the high NO-to-NO conversion yield of products, which is not suitable for the photocatalytic NO reaction. In this study, we modify g-CN by WO nanoplates for the first time for photocatalytic NO oxidation over a WO/g-CN composite to enhance the green product selectivity under atmospheric conditions.
