Amorphous BiSnxOy for Efficient CO2 Electroreduction to Formate via In Situ Doping

Advanced Science, EarlyView.
The amorphous BiSnxOy catalyst is electroreduced to Sn‐doped Bi during the electrochemical process. The Sn‐modulated Bi exhibits a favorable intermediate adsorption potential, leading to optimal catalytic efficiency. Remarkably, this catalyst demonstrates exceptional performance, achieving a Faradaic efficiency (FEformate) of 95.6% at 800 mA cm−2 in a ...

Meso‐Crowned Porphyrin as a Dual Cavity Hybrid Macrocycle for Improving the Efficiency and Stability of Perovskite Solar Cells

Advanced Science, EarlyView.
This study demonstrates a dual‐functional porphyrin‐based passivation molecule, [12]‐C‐4POR, capable of simultaneously coordinating Pb2+ and Li+ ions through its porphyrin core and crown ether moiety, respectively. This molecule effectively reduces trap‐state density, suppresses non‐radiative recombination, and mitigates Li+ migration at the perovskite/

In‐Wheel Piezoelectric DC Power Generator With Zero Resistive Torque

Advanced Science, EarlyView.
In this paper, we present a wheel‐shaped direct‐current piezoelectric generator (DC‐PG) that fundamentally overcomes these constraints by producing phase‐stable DC electricity directly from rolling motion. By embedding this system into suitcase wheels, we demonstrated a fully integrated real‐time location tracking system powered solely by mechanical ...

Ionic Highways under Multivariate‐Coupled Strategies: Ultrahigh Power Generation from Industrial Waste Liquors Using Robust COF Membranes

Advanced Science, EarlyView.
This study presents a multivariate‐coupled strategy to fabricate TB‐COF membranes with tunable charge density via uniformly distributed Bpy groups, enabling efficient ion transport and energy harvesting. The robust β‐ketoenamine‐linked structure ensures stability, achieving power outputs of 53.08 W m−2 (pH 4), 190.52 W m−2 (low‐grade heat), and 258.81 ...
