Microchanneled biomorphous Al2O3 coated with TiO2 aerogel for photocatalytic reduction of 4-nitrophenol

Copper-decorated iron oxide nanoparticles highly dispersed on coal-based activated carbons: a recoverable catalyst for the reduction of 4-nitrophenol, Congo red, and Rhodamine B

“…À and the contaminant molecules. [3][4][5][6] Currently, the catalysts used for the reduction of 4-NP mainly include noble metal-based catalysts (Ag, Au, Pt, Pd, etc.) and non-precious metal-based catalysts (Fe, Co, Ni, Cu, etc.).…”

“…A suitable catalyst is indispensable to lower the high kinetic barrier between the mutually exclusive negative ions BH 4 − and the contaminant molecules. 3–6 Currently, the catalysts used for the reduction of 4-NP mainly include noble metal-based catalysts (Ag, Au, Pt, Pd, etc. ) and non-precious metal-based catalysts (Fe, Co, Ni, Cu, etc.…”
