“…Like ZnO, MnZnO NPs did not show reduction activity (Figure S5c). More hydrogen ions are needed to reduce 4‐NP successfully, but the rate of hydrogen ions generation was very slow or insufficient in the case of ZnO and MnZnO NPs, so the reduction of 4‐NP did not occur (Abdullah, Gultom, et al, 2017; Abdullah, Kuo, et al, 2017; Gultom et al, 2017, 2018). The best photocatalytic activity was observed using MnCuZnO NPs catalyst that reduces 4‐NP in 36 min, as presented in Figure S5d.…”

The synergistic effect of bimetallic co‐incorporated metal oxides have gained enormous attention due to their unique optoelectronic properties. Herein, we present the green synthesis of ZnO, Cu‐incorporated ZnO, Mn‐incorporated ZnO, and Cu‐Mn co‐incorporated nanoparticles (ZnO NPs, CuZnO NPs, MnZnO NPs, MnCuZnO NPs) for antimicrobial and photocatalytic reduction applications using corn silk extract and industrial metal wastes. The as‐synthesized NPs were characterized by using UV‐visible absorption spectroscopy (UV‐Vis), photoluminescence (PL) spectroscopy, Fourier‐transformed infrared spectroscopy (FT‐IR), powdered x‐ray diffraction (XRD), and scanning electron microscopy (SEM). CuZnO, MnZnO, and MnCuZnO NPs efficiently inhibited bacterial culture growth. The photocatalytic reduction activity of as‐synthesized NPs against the different concentrations of 4‐nitrophenol (4‐NP) in water was also investigated. CuZnO and MnCuZnO nanoparticles were to be efficient photocatalysts for reducing 4‐NP into 4‐aminophenol (4‐AP).Research Highlights Green synthesis of nanomaterials by agricultural and industrial wastes Cu and Mn co‐incorporated ZnO NPs have shown good photocatalysis and antimicrobial activities Green approach for waste conversion to value‐added products

Ni‐incorporated CdS (Ni‐CdS) photocatalysts with different amounts of Ni dopant have been synthesized, characterized, and examined toward azo‐bond cleavages in visible‐light illuminated conditions. The optimum performance was achieved with a relatively low amount of Ni dopant (2 % atomic mass). The azo bonds of azobenzene (AB) and methyl orange (MO) compounds were hydrogenated with the in‐situ generated hydrogen on Ni‐CdS catalyst surfaces. The hydrogen evolution reaction was proved and measured with GC measurement during the photocatalytic session with an incandescent halogen lamp. Furthermore, the experimental data of UV‐vis spectra analyses suggested the formation of aniline or sodium sulfanilate and p‐aminodimethylaniline with the emerged peaks at ∼240 nm, indicating azo‐bond has been cleaved in AB or MO compounds, respectively. The catalytic performances of 2 % Ni‐CdS are also supported with electrical and photoresponse analyses. To demonstrate the possibility of industrial application, Ni‐CdS catalyst stability is also tested for several runs in reusability experiments and examined with cyclic voltammetry for 100 cycles without any significant degradation. The cleavage mechanisms of azo bonds in AB and MO compounds were discussed and proposed in this work.
