Membra membranes are a good candidate for membranes thanks to two-dimensional graphitic carbon nitride nanosheets' intrinsic in-plane nanopores. We present lamellar g-C 3 N 4 nanosheets as gas separation membranes with a disordered layer-stacking system based on top-up synthesis. Therefore, such lamellar membranes with high quality g-C 3 N 4 nanosheets have a great promise for gas separation applications.

The global epidemic of coronavirus disease caused by SARS-CoV-2 infection has posed a frightening situation. SARS-CoV-2's Spike protein may be a precursor to receptor binding and virus entry. Nanobody can obtain high-affinity binding to the spike protein for analysis as a recognition site. The maximum detection range of the PEC immunosensor was determined to be 1. 22 fg mLu20131.

Carbon nitride is an organic semiconductor with promising uses in solar energy conversion by photocatalytic water splitting. CN x's hard-terminated synthesis by filling mesoporous silica with small molecule precursors is one of the more common techniques for increasing CN x's productivity. Herein we present a new approach based on soluble acidified CN x nanosheets as the precursor in an attempt to minimize the risk of accidental chemical changes and better understand the intricate relationship between morphology and activity. We discovered that the silica-templated CN x with revised morphologies suffered from increased trap state densities and resulted in lower photocatalytic activity in comparison to CN x prepared without a template, which was supported by charge carrier dynamics studies. The chemical structure of the templated CN x obtained is not sensitive to changes in the silica template shape, according to characterization techniques.

Graphitic carbon nitride has long been used in the field of photocatalytic hydrogen production as a cost-effective photocatalyst. Consequently, the optimal photocatalytic hydrogen production rate for the modified graphitic carbon nitride is up three times to a value of 2390. 6 bcmol h -1 g -1, while apparent quantum yield reaches 8. 3 % at a wavelength of 420 nm. This work provides an innovative method for improving carbon nitride photocatalytic capacity as well as providing theoretical assistance for carbon nitride compounds' edge modification of carbon nitride compounds to increase hydrogen production efficiency.

A critical first step toward hydrogen production by electrochemical water splitting is to design and engineer effective electrode catalysts. By thermal refluxing, the nitride/reduced graphene oxide nanosheets are atomically embedded in ruthenium metal centers in the present study. This is largely due to the increased/reduced contribution of the Ru valence electrons to the state's density near the Fermi level, which controls both binding and reduction of hydrogen.

The modified carbon paste electrode demonstrated remarkable electrocatalytic action towards the electrochemical oxidation of ABZ in a phosphate buffer solution at pH 3 relative to a bare carbon paste electrode.
