In the agriculture field, the production yield is often less than the farmer's expected value because a few parts of the crops are damaged by pests and insects. Chemical pesticides have wide applications in the agriculture field. Through the agricultural run-off, these pesticides contaminate the water sources. So, there is a need for highly efficient La-doped ZnO photocatalytic material for pesticide degradation. Photocatalytic material was synthesized via a hydrothermal route. Zn (NO)3.6H2O and La (NO3)3.6HM2O was used as zinc and lanthanum precursor in ethanol. Surface Morphology and dopant composition were analyzed by SEM-EDX images which confirmed the hybrid of the metal doping process. [ABSTRACT FROM AUTHOR]

Chlorpyrifos insecticide is one of the most extensively used organophosphorus pesticides due to its low cost and excellent performance in controlling pests in agriculture fields and gardens. The presence of pesticides in the aquatic environment produces a slew of issues for both humans and ecosystems. The purpose of this research is to assess the photocatalytic detoxification of chlorpyrifos in wastewater utilizing g-C₃N₄/GO nanoparticles. The g-C₃N₄/GO nanoparticles were successfully synthesized by using calcinations and hydrothermal methods. Additionally, the photocatalytic detoxification of chlorpyrifos was examined by optimizing several parameters such as catalyst type, irradiation period, catalyst concentrations, and pH. The photocatalytic efficiency of g-C₃N₄/GO nanoparticles was determined by using a UV–visible spectrophotometer. According to the findings of this study, the photo detoxification effectiveness of chlorpyrifos pesticides rises with increasing illumination time, and detoxification of chlorpyrifos by using a photo-catalyst was strongly influenced by the operational parameters.

Rising pollution levels worldwide has moved governments to switch from carbon based fuels to alternative fuels. Hydrogen, a clean energy carrier can rightly be called as the fuel of future. Hydrogen is produced through various methods but water electrolysis is by far one of the most efficient approaches. Various expensive photocatalysts like Ag, Au, Pt, etc. are used during the process, which limits its commercial application. In this paper, our aim is to synthesize inexpensive high performance tantalum nitrite electrocatalyst on peanut shell biochar for H2 production through water electrolysis for improved photocatalytic activity. Ta3N5/Biochar was characterized using XRD, FTIR. [ABSTRACT FROM AUTHOR]

Complex vanadium oxide is an excellent multifunctional material. Various forms of vanadium oxide was synthesized out of them orthorhombic V2O5 form is more stable. In this manuscript hydrothermal process and mechanochemical process is adopted of the synthesised of Vanadium oxide in different morphological phases. The samples are characteristics by XRD methods using a hydrothermal technique, the V2O5 precursor was successfully synthesised by mixing NH4VO3 and C2H2O4 in a 1:1 molar concentration ratio and conducted the reaction at 150 °C for 7 hours. The orthorhombic phase V2O5 formation is confirmed by the X-ray diffraction. The position of the peak and the quality of the phase formation is tabulated in the paper. Hydrothermal method displays high crystalline belt like formation while mechanochemical method shows formation of nano-particle with deteriorated degree of crystalline confirmed by SEM. The synthesis of high crystalline vanadium oxide orthorhombic phase in different morphologies opens up a way to utilize such materials towards the energy storage and sensing applications.
