Abstract A graphite oxide (GO) semiconductor photocatalyst with an apparent bandgap of 2.4–4.3 eV is synthesized by a modified Hummers' procedure. The as‐synthesized GO has interlayer spacing 0.42 nm because its moderate oxidation level. Under irradiation UV or visible light, this steadily catalyzes H 2 generation from 20 vol % aqueous methanol solution and pure water. As the sheets extensively disperse in water, cocatalyst not required for over photocatalyst. During photocatalytic reaction,...

Abstract Microsupercapacitors (MSCs) with neutral multivalent electrolytes are safer, cheaper, and exhibit higher theoretical energy densities compared the MSCs acidic alkaline electrolytes. Multivalent charge carriers (e.g., Mg 2+ , Zn ) in Ti 3 C 2 T x MXene electrodes have not been demonstrated, which could theoretically achieve specific capacitances densities. However, because of larger size carriers, require further modifications to facilitate reversible electrochemical reactions....
