Understanding the Role of Copper Oxidation State on a TiO2/ZSM‐5 Catalyst for Photocatalytic CO2 Reduction to Methanol

open access: yesAdvanced Materials Interfaces, EarlyView.
The influence of copper oxidation states on TiO₂/ZSM‐5 catalysts is investigated for photocatalytic CO2 reduction to methanol. A Cuδ⁺‐modified Ti₂/ZSM‐5 catalyst (CTZ‐1) exhibits superior activity due to enhanced electronhole separation, the presence of Ti3⁺, and a core–shell structure.

Nanohybrid of Silver‐MXene: A Promising Sorbent for Iodine Gas Capture from Nuclear Waste

open access: yesAdvanced Materials Interfaces, EarlyView.
Silver‐MXene (Ag‐Ti3C2Tx) nanohybrids effectively captured iodine gas at 150 °C, with Ag nanoparticles loaded onto MXene via silver nitrate reduction. Upon exposure to iodine gas, silver iodide forms, confirming successful adsorption. Ag‐Ti3C2Tx shows superior iodine uptake (946 mg g−1) compared to conventional sorbents, demonstrating its potential as ...

Synthesis of Bimetallic (Iron–Cobalt) Single Atom Catalysts for Electrochemical Detection of Nitrites

open access: yesAdvanced Materials Technologies, EarlyView.
A CO2 laser‐assisted solid‐state synthesis of a bimetallic single‐atom catalyst is presented. The resulting material consists of a 3D porous graphene support with iron and cobalt atoms anchored as single atoms. Through electrochemical methods, the material's efficiency is demonstrated in the sensitive and selective determination of nitrite, mimicking ...

The Importance of Metal Ion Impurity Bands in the Photoluminescence of Halide Double Perovskites

open access: yesAdvanced Optical Materials, EarlyView.
Many publications have associated emission spectral features of double perovskite halides in the region at 460–470 nm with “pristine” materials. This leads to not only false observations but also incorrect conclusions concerning the transformation of dark into bright excitons or boosting self‐trapped exciton emission.
