A high recombination rate and low charge collection are the main limiting factors of copper oxides (cupric and cuprous oxide) for the photocatalytic degradation of organic pollutants. In this paper, a high performance copper oxide photocatalyst was developed by integrating cupric oxide (CuO) and cuprous oxide (CuO) thin films, which showed superior performance for the photocatalytic degradation of methylene blue (MB) compared to the control CuO and CuO photocatalyst. Our results show that a heterojunction photocatalyst of CuO-CuO thin films could significantly increase the charge collection, reduce the recombination rate, and improve the photocatalytic activity.

The unique optical properties of perovskite quantum dots (PQDs), particularly the tunable photoluminescence (PL) across the visible spectrum, make them a promising tool for chlorinated detection. However, the correlation between the fluorescence emission shift behavior and the interface of phase transformation in PQDs has not been thoroughly explored. In this study, we synthesized CsPbBr PQDs via the hot-injection method and demonstrated their ability to detect chlorinated volatile compounds such as HCl and NaOCl through a halide exchange process between the PQDs' solid thin film and the chlorinated vapor phase.

Energy crisis and environmental pollution are two central themes of contemporary research towards achieving sustainable development goals (SDGs). Material chemistry is the chief discipline that can resolve glitches in these areas through the appropriate design of chemical compounds with multifunctional properties. In this regard, two stable coordination polymers (CPs) were synthesised in this work using Zn(II) (3d) and Cd(II) (d) metal nodes with 1,4-benzenedicarboxylate () as the bridging ligand and monodentate pyridyl-N coordinated 9-fluoren-2-yl-pyridin-4-ylmethylene-amine (flpy) as the fluorogenic partner.

Polymeric membranes with great processability are attractive for the H/CO separation required for hydrogen production from renewable biomass with carbon capture for utilization and sequestration. However, it remains elusive to engineer polymer architectures to obtain desired sub-3.3 Å ultramicropores to efficiently sieve H from CO.

Cupric oxide (CuO) is a promising p-type semiconducting oxide used in many critical fields, such as energy conversion and storage, and gas sensors, which is attributed to its unique optoelectrical properties and cost-effectiveness. This work successfully deposited amorphous, pinhole-free, ultrathin CuO films using atmospheric pressure spatial atomic layer deposition (SALD) with copper(II) acetylacetonate and ozone as precursors. The growth rate increased from 0.
