Polaron conductivity in α-Fe2O3 quenched by adsorbed NO2

Polaron-mediated charge transport in α–Fe 2 O 3 plays a central role in its performance as a gas-sensing material, yet the atomistic interaction between surface adsorbates and polarons remains insufficiently understood. Here, density functional theory with Hubbard-U correction (D...

MOF–biochar composites for wastewater treatment: A review on synthesis, properties, and adsorption mechanisms

Industrial wastewater containing heavy metals, dyes, and emerging contaminants remains difficult to treat using conventional adsorbents due to limited selectivity and insufficient active sites. Recently, metal-organic framework-biochar (MOF–BC) composites have emerged as promisin...
