“…40 The 15 other modes are at A1 (278 cm -1 ), A3 (509 cm -1 ) and A1 (LO) (580 cm -1 ) can be assigned to local vibration modes (LVMs) of nitrogen in ZnO. 41 Raman modes at 278 cm -1 was attributed to the localized vibration of Zn atoms, where parts of their first nearest oxygen atoms are partly replaced by nitrogen atom in the ZnO 20 lattice. 42 Also, the Raman peaks observed at 509 and 580 cm -1 is related to the presence of nitrogen.…”

“…After careful evaluation of the above all results, the over-all 20 formation mechanism of C, N and S-doping either in mixed ZnO/ZnS or in ZnO phase by the 'thiourea route' can be visualized by Equation 1 and Scheme 1. When zinc acetate and thiourea are mixed in alcoholic medium (methanol) at room temperature, BTZA complex is formed.…”

“…The degradation of lignin conferred the useful fine chemical as a by-product i.e.1-Phenyl-3-buten-1-ol. From this, 20 we can achieve maximum clean energy (H 2 production) and at the same time environmental problems caused by lignin contamination in water can be minimised.…”

Herein,we have reported the simultaneous water splitting and lignin (biomass) degradationbyC, N and Sdoped ZnO nanostructured material.Synthesis of C, N and S-doped ZnO was achieved viacalcination of Bis-thiourea zinc acetate (BTZA) complex. Calcination of the complex at 500 o C results in formation of 10 C, N, and S-doping in mixed phase of ZnO/ZnS, while calcination at 600 o Cgives the single phase of ZnO with N and S doping which is confirmed by XRD, XPS and Raman spectroscopy. The band gap of the calcinedsamples was observed to be in the range of 2.83-3.08 eV.Simultaneous lignin (waste of paper and pulp mills) degradation and hydrogen(H 2 ) production via water splitting under solar light has been investigated which is hitherto unattempted. The utmost degradation of lignin was observed with the 15 sample calcined at 500 o Ci.e. C, N, S-doped ZnO/ZnS as compared to sample calcined at 600 o Ci.e. N and S doped ZnO. The degradation of lignin confer the formation of useful fine chemical as a by-product i.e. 1-Phenyl-3-buten-1-ol. However, excellent H 2 production i.e. 580, 584 and 643 µmole h -1 per 0.1g, was obtained for the sample calcined at 500, 550 and 600 o C, respectively. The photocatalytic activity obtained is much higher as compared to earlier reported visible light active oxide and sulfidephotocatalysts. The 20 reusability study shows good stability of the photocatalyst. The prima facie observations show that lignin degradation and water splitting is possible with the same multifunctional photocatalystwithout any scarifying agent.

“…Among oxide metals, zinc oxide (ZnO) nanoparticle has attracted more attention because the zinc oxide nanoparticle is a promising material for applications in sensors, magnetics, electronics, and photocatalysis. In the past decade, ZnO-based materials had been focused on for a candidate for electromagnetic (EM) wave absorption due to their excellent dielectric properties [3,4], semiconductive properties [5], selectable mechanical properties [6] for a typical structural absorber, and large-scale synthesis [7,8].…”

Spawns structure of rod-like ZnO wrapped in the cellulose nanofibers was successfully fabricated through a facile one-step hydrothermal method, and their electromagnetic wave absorption properties were investigated. The structure and properties of the composite aerogel were characterized. The enlarged morphology images showed that the as-prepared cellulose nanofiber/ZnO samples were spawns structure of rod-like ZnO wrapped in the cellulose nanofibers. The composite aerogel in a wax matrix exhibited excellent electromagnetic wave absorption performance over 2–18 GHz. The widest absorption bandwidth of 30 wt% contained with reflection loss values less than −10 dB was up to 12 GHz (6–18 GHz) at the thickness of 5.5 mm and the minimum reflection loss value reached −26.32 dB at 15.2 GHz when the thickness of the absorber was 3 mm.

“…Several photocatalytic semiconductor materials, such as TiO 2 and ZnO, have been widely used, but they have the limitation that they can only absorb ultraviolet light, which accounts for just a tiny portion of the sunlight [4][5][6][7][8]. In recent years, bismuth oxybromide (BiOBr) has received much attention due to its potential photocatalytic abilities under visible light [9].…”
