Access to drinkable water is becoming more and challenging due worldwide pollution the cost of treatments. Water wastewater treatment by adsorption on solid materials usually cheap effective in removing contaminants, yet classical adsorbents are not sustainable because they derived from fossil fuels, can induce secondary pollution. Therefore, biological sorbents made modern biomass increasingly studied as promising alternatives. Indeed, such biosorbents utilize waste that would otherwise pollute systems, promote circular economy. Here we review biosorbents, magnetic sorbents, other cost-effective with emphasis preparation methods, types, mechanisms, regeneration spent adsorbents. Biosorbents prepared a wide range materials, including wood, bacteria, algae, herbaceous agricultural waste, animal waste. Commonly removed contaminants comprise dyes, heavy metals, radionuclides, pharmaceuticals, personal care products. Preparation methods include coprecipitation, thermal decomposition, microwave irradiation, chemical reduction, micro-emulsion, arc discharge. Adsorbents be classified into activated carbon, biochar, lignocellulosic clays, zeolites, peat, humic soils. We detail isotherms kinetics. Regeneration supercritical fluid desorption. also discuss exhausted adsorbent management disposal. found agro-waste remove up 68–100% while wooden, herbaceous, bacterial, marine-based 55–99% metals. Animal waste-based 1–99% The average removal efficiency modified around 90–95%, but some treatments, cross-linked beads, may negatively affect their efficiency.

Catalysis stands as a cornerstone in chemical synthesis, pivotal advancing sustainable manufacturing pathways. The evolution from energy-intensive to catalytic processes has marked transformative shift, notably exemplified by low-energy methods. These processes, operating under milder conditions and emphasizing selectivity recyclability, represent the forefront of chemistry. This review navigates through an array reactions, highlighting their diverse applications culminating exploration recent strides within processes. For example, explores uses such enzyme mimicking, biodiesel production, carbon dioxide capture, organic synthesis. Additionally, it covers enzymatic catalysis photocatalysis for transformations, energy applications, water treatment. Notably, emphasizes capabilities single-atom (SAC) diatomic catalysts (DACs), recognizing exceptional performance catalyzing reactions at minimal activation energies while maintaining high efficiency mild conditions. By elucidating modulation electronic structure offering microelectronic perspective, aims elucidate mechanisms underlying activity SAC DACs. Emphasizing interplay between coordination chemistry principles efficacy, elucidates indispensable role complexes fortifying sustainability these spotlighting fusion with catalysis, this underscore collective influence shaping landscape production.

Abstract The presence of pharmaceuticals in ecosystems is a major health issue, calling for advanced methods to clean wastewater before effluents reach rivers. Here, we review adsorption remove ibuprofen, with focus on ibuprofen occurrence and toxicity, adsorbents, kinetics, isotherms. Adsorbents include carbon- silica-based materials, metal–organic frameworks, clays, polymers, bioadsorbents. Carbon-based adsorbents allow the highest from 10.8 408 mg/g activated carbon 2.5–1033 biochar. Metal–organic frameworks appear promising due their high surface areas tunable properties morphology. 95% published reports reveal that kinetics follow pseudo-second-order model, indicating predominantly governed by chemical adsorption. 70% disclose Langmuir model describes isotherm, suggesting involves monolayer
