Abstract The energy crisis and environmental pollution have recently fostered research on efficient methods such as catalysis to produce biofuel clean water. Environmental refers green catalysts used breakdown pollutants or chemicals without generating undesirable by-products. For example, derived from waste inexpensive materials are promising for the circular economy. Here we review photocatalysis, biocatalysis, electrocatalysis, with focus catalyst synthesis, structure, applications. Common include biomass-derived materials, metal–organic frameworks, non-noble metals nanoparticles, nanocomposites enzymes. Structure characterization is done by Brunauer–Emmett–Teller isotherm, thermogravimetry, X-ray diffraction photoelectron spectroscopy. We found that water can be degraded an efficiency ranging 71.7 100%, notably heterogeneous Fenton catalysis. Photocatalysis produced dihydrogen (H 2 ) generation rate higher than 100 μmol h −1 . Dihydrogen yields ranged 27 88% methane cracking. Biodiesel production reached 48.6 99%.

Rapid growth in socio-economic requirements and climatic change has put much pressure on the quality of water resources. To prevent future shortage fresh to keep up with current demand for water, wastewater reuse, recycling are among most pressing issues that must be addressed immediately. So far, many technologies have been used remove both inorganic organic pollutants from wastewater. Unfortunately, modern treatment still out reach financially developing nations, making it difficult them eliminate these toxins. Moreover, increasing environmental toxicity solid waste exposures is also a major cause worry. Intending combat issues, research efforts increased develop an efficient, eco-friendly low cost biosorbent agricultural treat As result, there focus identifying locally regionally accessible agriculture wastes removal heavy metals/metalloids dyes. This article aims review multidisciplinary approach handle as potential resource treatment. A comprehensive discussion included fundamentals biosorption involved mechanism. The strategies improve efficiency biosorbents discussed. In addition, developments various derived different their application toxic elements using diverse methods reviewed set stage further investigation. Finally, regeneration challenges implement addressed. will help bridge gap between laboratory findings industrial application, leading development more efficient systems removing pollutants.

Plastic and biomass waste pose a serious environmental risk; thus, herein, we mixed with plastic bottle (PET) to produce char composite materials for producing magnetic better separation when used in water treatment applications. This study also calculated the life cycle impacts of preparation adsorbent material 11 different indicator categories. For 1 functional unit (1 kg pomace leaves as feedstock), abiotic depletion fossil fuels global warming potential were quantified 7.17 MJ 0.63 CO2 equiv production materials. The (MPBC) was then remove crystal violet dye from its aqueous solution under various operational parameters. kinetics isotherm statistical theories showed that sorption CV onto MPBC governed by pseudo-second-order, Langmuir models, respectively. quantitative assessment capacity clarifies produced exhibited an admirable ability 256.41 mg g-1. Meanwhile, recyclability 92.4% demonstrated after 5 adsorption/desorption cycles. Findings this will inspire more sustainable cost-effective sorbents, including those derived combined streams.
