Facile fabrication of CuO-Pb 2 O 3 nanophotocatalyst for efficient degradation of Rose Bengal dye under visible light irradiation

Photocatalytic Decomposition of Nitrobenzene in Aqueous Solution by Ag/Cu2O Assisted with Persulfate under Visible Light Irradiation

“…The "n" parameter was set at the value of 1/2 according to the electronic transition state of Ag/Cu 2 O semiconductors. The draft of (αhν) 2 varied with incident optical energy; (hν) was drawn to obtain the band gap energy by intercepting tangent lines to the X-axis[53][54][55]. Consequently, the Cu 2 O band gap energy was determined to be 2.17 eV, consistent with that reported by Muthukumaran et al[56].…”

Construction of an α-Fe2O3/Bi2O3 p–n heterojunction with exceptional visible-light photocatalytic performance for dye removal

“…Sun et al 17 synthesized a spindle-like α-Fe 2 O 3 /Bi 2 O 3 core–shell heterostructure with tremendous photocatalytic performance in the degradation of Rhodamine B (RhB) under visible light illumination. Kamaraj et al 18 reported a p-type CuO/n-type Pb 2 O 3 photocatalyst fabricated using a wet chemical method. The photocatalytic ability of the CuO/Pb 2 O 3 heterojunction was evaluated by degrading Rose Bengal under visible-light illumination.…”

Photocatalytic degradation of nitrobenzene in wastewater by persulfate integrated with Ag/Pb3O4 semiconductor under visible light irradiation

“…The “n” value was set at the value of 1/2 based on the electronic transition state of semiconductors. The variation of (αhν) 2 versus incident energy (hν) was plotted to procure the band gap energy by intercepting the tangent to the X-axis ( Maji et al., 2011 ; Štengl and Grygar, 2011 ; Kamaraj et al., 2018 ). Thus, the band gap energy of Pb 3 O 4 was estimated to be 2.20 eV, corresponding to the publication ( Sharon et al., 1986 ).…”
