The development of a green and environmentally friendly photocatalytic multifunctional coating in the field architectural coatings is crucial. To this end, simple hydrothermal method was constructed for growth MoS2 situ on modified MoO3, with full-spectrum elimination bacterial formaldehyde, using waste bioresource eggshells as substrate MoO3@MoS2 photocatalyst. prepared has an excellent antibacterial effect Gram-positive bacteria represented by S. aureus Gram-negative E. coli also significant effectiveness formaldehyde. generates electron–hole pairs, formation S-heterojunctions demonstrated XPS under xenon lamp (0.28 W/cm2) irradiation increases photogenerated pair separation improves performance coating. Combining photothermal increased specific surface area discarded to enhance adsorption properties, showed almost 99.9% antimicrobial resistance against within 10 min. At same time, rate high concentrations formaldehyde about 92.5% 30 This offers promising strategy secondary use bioresources coatings.

Abstract The scarcity of fresh air, drinking water, and soil is a matter serious concern worldwide owing to the presence organic pollutants in environment. dye, such as methylene blue (MB) have enormous toxic effects on environment human health. Therefore, degradation non-biodegradable dyes very important reduce toxicity water and-a step towards waste management systems. This paper focuses MB dye using carbon quantum dots (CQDs). CQDs were synthesized by microwave irradiation method citric acid L-cysteine precursor confirmed X-Ray Diffraction (XRD), Raman Spectrum, Fourier Transform Infrared Spectroscopy (FTIR) Energy Dispersive x-ray (EDX) spectroscopy techniques. optical properties 2.56 nm, investigated UV-visible technique absorption peak appeared at 340 nm which corresponding n → π * transition. In photoluminescence (PL) spectra analysis, highest emission was obtained 440 when excited 345 nm. used for distilled percentage calculated found be 99.17% 90 min under UV light irradiation. Also, studied impact degraded seed germination Cicer arietinum (black gramme) growth rate 15%–20% more than containing water.
