Nanocrystals doped with 7.2 atom% Al show the activity of 53 μmol H2 per hour under 240 mW cm−2 UV illumination and an AQE of 0.06% at 375 nm. Based on surface photovoltage spectroscopy (SPS), aluminum enhances photochemical charge separation in the Al:SrTiO3 nanocrystals and reduces ...
Draw the Lewis structure of the formate ion, HCO_2-. (Assign lone pairs, radical electrons, and atomic charges where appropriate.) Draw Lewis structures for the molecule N2H4 and the nitrate ion NO3-. Draw the Lewis st...
Many chemical reactions occur in aqueous solution based on water as a solvent, which highly prefers solutes with polar bonds or net positive/negative charges. An ionic equation is a type of chemical reaction equation (typically in aqueous solution...
These beneficial properties were attributed to the special self-assembly structure of highly active MoNi4 nanoalloy mosaiced on MoO2 ultrathin nanosheets. 2. Experimental 2.1. Synthesis of electrodes Ni(NO3)2·6H2O and NaMoO4·2H2O were purchased from Shanghai Aladdin and used as received. The ...
Moreover, the robust interfacial interaction and electronic coupling between MOF and Ti3C2Tx nanosheets facilitate fast charge transfer kinetics and provide a stable structure, both crucial factors in optimizing catalytic performance [19]. The CoNi0.04- MOF-74/MXene/NF composite exhibits superior ...
