Pollutant treatment, hazardous solid waste conversion, and biomass resource utilization are significant topics in environmental pollution control, simultaneously achieving them is challenging. Herein, we developed a "from absorbent to effective photocatalyst" upcycle strategy for nontoxic conversion of Cd(II) adsorbed on thiolation@wood-aerogel (TWA) into CdS/g-C3N4 heterojunctions through the situ chemical deposition high-temperature carbonization combined method overcome above problems simultaneously. We used Schiff base reaction graft l-cysteine dialdehyde@wood-aerogel prepare TWA with high adsorption capacity (600 mg/L, 294.66 mg/g). Subsequently, spent Cd(II)-loaded-TWA was as substrate construction heterojunction activating peroxymonosulfate (PMS) under simulated sunlight [simulated solar light (SSL)], efficient tetracycline (TC) degradation (20 95.32%). The Langmuir pseudo-second-order models indicate single-layer process. In PMS/SSL system, CdS/g-C3N4@TWA efficiently rapidly degraded TC via an adsorption-photocatalytic synergistic mechanism. has good biocompatibility. This study proposed design preparation new type wood aerogel provided novel upcycling innovative use adsorbent.

Abstract Developing catalysts with suitable adsorption energy for oxygen‐containing intermediates and elucidating their internal structure‐performance relationships are essential the commercialization of Li–O 2 batteries (LOBs), especially under high current densities. Herein, NiCo O 4 ‐CeO heterostructure a spontaneous built‐in electric field (BIEF) is designed utilized as cathode catalyst LOBs at density. The driving mechanism electron pumping/accumulation heterointerface studied via experiments density functional theory (DFT) calculations, growth discharge products. results show that BIEF induced by work function difference optimizes affinity LiO promotes formation nano‐flocculent Li , thus improving performance Specifically, exhibits large capacity (9546 mAh g −1 4000 mA ) stability (>430 cycles ), which better than majority previously reported metal‐based catalysts. This provides new method tuning nucleation decomposition inspires design ideal to operate

Developing low-cost, sustainable catalysts is critical to meet the green-transition goal in water treatments. Herein, a common metal modified g-C3N4 material (FeMg-O-g-C3N4) was designed improve electron mobility and peroxymonosulfate (PMS) utilization. Likewise, surface acidification of has introduced extra porous structure, anchor sites for metals, activate sites. This new catalyst free expensive rare-earth metals creates numerous micro-electric fields through: 1) large difference electronegativity Fe (1.83) Mg (1.31); 2) cation-π effect formed between benzene-like ring structure g-C3N4; 3) added PMS pollutant (tetracycline (TC)) as provider promoting transfer electrons electron-rich Both non-radical (1O2) radical (surface-bound ·OH SO4·−) pathways contribute degradation. Given promising results stability catalyst, this study opens horizons apply over expensive, toxic rare PMS-based
