Abstract The valorization of municipal solid waste permits to obtain sustainable functional materials. As the urban population burgeons, so does volume discarded waste, presenting both a challenge and an opportunity. Harnessing materials latent energy within this not only addresses issue disposal but also contributes innovation with applications in energy, electronics, environment sectors. In perspective, technologies for converting, after sorting, into valuable metals, chemicals, fuels are critically analyzed. Innovative approaches convert organic carbon create, from plastic electronic wastes, metal–organic frameworks conversion, storage, CO 2 adsorption conversion proposed. Green hydrometallurgy routes that permit recovery precious metals avoiding noble metals’ oxidative leaching, thus their downcycling, highlighted. reclaimed hold promise use optoelectronic devices.

Light-driven bioethanol dehydration offers attractive outlooks for the sustainable production of ethylene. Herein, a surface-hydrogenated CrMnOx is coupled with GaN nanowires (GaN@CMO-H) light-driven ethanol to Through combined experimental and computational investigations, surface hydrogen-replenishment mechanism proposed disclose pathway over GaN@CMO-H. Moreover, GaN@CMO-H can significantly lower reaction energy barrier C2H5OH-to-C2H4 conversion by switching rate-determining step compared both GaN@CMO. Consequently, illustrates considerable ethylene activity 1.78 mol·gcat−1·h−1 high turnover number 94,769 mole per CrMnOx. This work new route only use sunlight beyond fossil fuels. presents promising production. study unveils facilitating on CrMnOx, achieving an rate mol·gcat−1·h−1.

Abstract Replacing fossil fuels by renewable biomass enables green syngas production in an effort to achieve carbon neutrality and sustainable circular processes. Here, inexpensive catalyst of Ni nanoparticles supported on SiO 2 modified La 3+ (Ni/La 0.10 –S) is presented, exhibiting exceptional H CO rates (4051.4 2467.8 mmol g −1 h , respectively) with 7.7% light‐to‐fuel efficiency cellulose steam reforming (SR), merely under focused illumination. Excellent performance mainly attributed photothermal catalysis resulting from the strong solar absorption high conversion nanoparticles. The mitigation tar char formation significantly benefits O involvement reaction, which substantially improved addition enhancing sorption. Remarkably, illumination exerts mere photoactivation during primarily pronounced activation Ni─O bonds at surface. Particularly, Ni–O–La moieties, combination species replenishment O, makes Ni/La –S superior Ni/SiO . synergy promotion Ni–O poses a promising strategy for efficient catalytic SR syngas.

ConspectusFor sustainable development, exploring renewable resources is an urgent priority. Nonfood biomass, one of the largest on Earth, primarily comprises three key components: lignin (ca. 15-30%), cellulose 35-50%), and hemicellulose 20-30%). Theoretically, nonfood biomass can be converted into green chemicals energy. However, most studies have focused generation carbon-based energy under harsh conditions, often resulting in lower selectivities. Therefore, further efforts to explore efficient selective methods for producing hydrogen (H2) are essential promoting practical applications biomass. In this Account, we summarize our contributions transformation its derivatives aryl compounds H2. These transformations were achieved using visible-light-induced photocatalytic systems that generate active radicals selectively cleave C-C, C-O, C-H, O-H bonds mild without noble metals. First, compound production was by chemoselective cleavage C-C C-O carboxyl ether radical cations. Specifically, charge-transfer complex induced carboxylic acids, which platform molecules derived from oxidation; free form facilitated model 4-O-5 linkage. Moreover, arenols alcohols obtained via cooperation cation vanadate-induced models various linkages. Second, developed a streamlined strategy H2 one-pot, two-step route with formic acid (HCO2H) as intermediate storage thermocatalysis. Using photoredox catalysis, HCO2H initially alkoxy radical-induced gradual cellulose, hemicellulose, glucose, their derivatives. Subsequently, biomass-based realized hydroxyl (·OH)-induced C-H following bonds, nickel catalysis. Third, highest capability water reforming. This process utilized followed generated carbon cations electrocatalysis, inducing well-organized O-H, bonds. We anticipate these insights will inspire development more efficient, stable, cost-effective catalytic systems, accelerating utilization resource driving other related significant transformations.
