Advanced Energy Materials, EarlyView.Aliovalent B‐site substitution with Sn2+ in lead‐free perovskite, Cs3Bi2Br9, is employed to simultaneously induce lattice contraction and bromine vacancy through charge imbalance and ionic radius mismatch. The resulting structural distortion modulates the electronic structure and improves charge separation, leading to enhanced visible‐light‐driven CO2 ...

Three-Dimensional Simulation-Based Optimum Design of Direct Methanol Fuel Cell System
, 2013 A three-dimensional, single-phase, multicomponent mathematical model is used for the analysis of a liquid-fed direct methanol fuel cell. Liquid phase is considered on the anode side, and gas phase is considered on the cathode side.

Surface‐Functionalized MXene for Enhanced Photocatalytic CO2 Reduction
Advanced Energy Materials, EarlyView.Poly(catechol/p‐cresol)‐functionalized MXene (f‐MXene) enhances oxidation stability while preserving conductivity, enabling efficient interfacial electron transfer in a Cu/f‐MXene/reduced TiO2 photocatalyst. Strong Cu–f‐MXene synergy promotes CO2 activation and selective CH4 production, achieving a CH4 yield of 18.1 µmol g−1 (>200 × vs.

Sonocatalytic carbon dioxide reduction for syngas production over surface‐roughened CuxO catalyst
AIChE Journal, EarlyView.Abstract The transition to a carbon‐circular economy requires efficient technologies for converting CO2 into value‐added chemical feedstocks. Sonocatalytic CO2 conversion has recently emerged as a compelling approach to drive this conversion. Here, we report a surface‐roughened CuxO catalyst for sonocatalytic CO2 reduction in aqueous media, achieving a

Machine learning driven many‐objective moving horizon scheduling optimization
AIChE Journal, EarlyView.Abstract Industrial electrification can decarbonize chemical manufacturing, but it exposes operations to volatile electricity prices and carbon intensities. This work develops a machine learning‐enhanced many‐objective moving horizon scheduling framework that predicts objective correlation groupings from 48‐hour price and emission‐intensity profiles ...

Modeling the direct methanol fuel cell
, 2012 The Direct Methanol Fuel Cell (DMFC) is simulated in sequential mode in a zero-dimensional model using Butler-Volmer equations to represent the electro-chemical reactions on both electrodes. It is shown that this approach is able to predict the harmful methanol flow across the polymer electrolyte membrane (PEM) - the so called crossover - and the ...
