Enhanced Urea Oxidation Reaction by Mn‐Doped Nickel Hydroxide From Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mn incorporation modifies the hydroxide structure and modulates the electronic properties of the Ni centers, promoting the formation of catalytically active NiOOH species. Mn dopants induce a favorable electronic effect but do not directly participate in the UOR mechanism, enhancing the overall urea oxidation rate and resulting in increased hydrogen ...

Selecting Between Hydrogen and Methanol for Fuel Cell‐Organic Rankine Cycle Hybrid Power Systems: A Comparative 4E Analysis

Energy Science &Engineering, EarlyView.
A 4E comparison of PEMFC‐ORC and DMFC‐ORC systems shows that PEMFC‐ORC achieves 21% higher energy efficiency, while DMFC‐ORC obtains 31% higher exergy efficiency and 57% lower levelized cost of electricity. However, DMFC‐ORC emits nearly twice the annual carbon dioxide equivalent of PEMFC‐ORC.
