High‐Performance Electrocatalysts of Potassium Lactate Oxidation for Hydrogen and Solid Potassium Acetate Production

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Potassium lactate, produced from polylactic acid plastic waste, is oxidized to potassium acetate on an anode using Ni(Co)OOH as the electrocatalyst, while hydrogen is simultaneously generated at the cathode, through a highly efficient industrial‐scale electrolysis system.

Challenges and Opportunities of Upconversion Nanoparticles for Emerging NIR Optoelectronic Devices

open access: yesAdvanced Materials, EarlyView.
The special photo‐responsiveness of upconversion nanoparticles has opened up a new path for the advancement of near‐infrared (NIR)‐responsive optoelectronics. However, challenges such as low energy‐conversion efficiency and high nonradiative losses still persist.

Surface Engineering of PtSe2 Crystal for Highly Efficient Electrocatalytic Ethanol Oxidation

open access: yesAdvanced Materials, EarlyView.
2D PtSe2 has been demonstrated as high‐performance catalyst for electrocatalytic ethanol oxidation. Plasma treatment engineers the surface of single‐crystalline PtSe2 by removing Se atoms, resulting in the exposure of PtSe2 (101) facet. Excellent EOR activity and poison‐resistance are demonstrated, which is rationalized by in situ electrical transport ...

Revealing Trapped Carrier Dynamics at Buried Interfaces in Perovskite Solar Cells via Infrared‐Modulated Action Spectroscopy with Surface Photovoltage Detection

open access: yesAdvanced Materials, EarlyView.
A new spectroscopy technique (i.e., pump‐push‐surface photovoltage) is introduced that monitors trapped carrier dynamics at the buried interfaces in perovskite solar cells (PeSCs) via combining optical trap activation by infrared light with surface photovoltage detection.

Electron Extraction Optimization for Carbon‐Based Hole‐Conductor‐Free Perovskite Photovoltaics With Record 1.41 V VOC

open access: yesAdvanced Materials, EarlyView.
A gradient electron energy level strategy is constructed to reduce voltage losses in planar HTL‐free CsPbI2Br C‐PSCs. This electron extraction optimization enables rapid photogenerated electron extraction and carrier separation, thereby suppressing recombination at the back contact. The resulting PSCs deliver a record VOC of 1.41 V, a high PCE of 17.42%
