Materials that are capable of extracting gold from complex sources, especially electronic waste (e-waste) with high efficiency needed for resource sustainability and effective e-waste recycling. However, it remains challenging to achieve extraction capacity trace amount gold, precise selectivity over a wide range co-existing elements. Here we report reduced graphene oxide (rGO) material has an ultrahigh amounts (1,850 mg/g 1,180 10 ppm 1 gold). The excellent behavior is accounted the areas...
Abstract A strategy for in situ generation of furan‐based ortho ‐quinodimethanes ( o ‐QDMs) by the gold(I)‐mediated dehydrogenative heterocyclization 2‐(1‐alkynyl)‐2‐alken‐1‐ones presence pyridine N ‐oxide under mild reaction conditions was developed. These ‐QDMs were trapped electron‐deficient olefins and alkynes, thus furnishing various 2,3‐furan‐fused carbocycles good yields with high diastereo‐ regioselectivities.
Development of a p–n heterojunction to achieve efficient degradation organic pollutants is promising approach in the field photocatalysis. Herein, BiVO4 with bioinspired hierarchical structures was prepared sol–gel method and combined BiOCl nanoplates construct 3D/2D configuration via an situ deposition route. The served as excellent substrate uniform loading nanoplates. obtained BiVO4/BiOCl hybrids exhibited significantly enhanced photocatalytic efficiency for degrading phenol under visible...
The photoelectrochemical (PEC) water reduction performance of CuBi2O4 (CBO)-based photocathodes is still far from their theoretical values due to low bulk and surface charge separation efficiencies. Herein, we propose a regrowth strategy prepare photocathode with CBO coating on Zn-doped (CBO/Zn-CBO). Furthermore, NaBH4 treatment CBO/Zn-CBO introduced oxygen vacancies (Ov) CBO/Zn-CBO. It was found that Zn-doping not only increases the carrier concentration CBO, but also leads appropriate band...

Abstract A comprehensive evaluation of collagen-based historical artifacts is crucial for the preservation and inheritance cultural relics, necessitating interdisciplinary approaches that integrate scientific knowledge with practical expertise to develop effective conservation strategies. The present work was focused on a piece leather armor housed in Turpan Museum, Xinjiang, China. SEM–EDS, XRD, ATR-FTIR, NMR were carried out this from macro micro perspectives, mainly including morphology...
Abstract The environmental occurrence of anthropogenic chemicals, especially persistent micropollutants per- and poly-fluoroalkyl substances (PFAS) raises pressing concerns for global drinking water safety. Adsorption is an effective technology removing PFAS, but limited by unsatisfactory adsorption capacity efficiency. We report a strategy to attach polyamine adlayers graphene oxide (GO) nanosheets, that produces highly-charged monodispersed two-dimensional (2D) adsorbents GO nanosheet...
ABSTRACT The increasing accumulation of e‐waste containing precious metals calls for the development efficient recycling strategies gold recovery from e‐waste. In this study, we present scalable fabrication (up to 3600 cm 2 ) rGO/cellulose composite papers with a high rGO areal density 7.5 g/m and their use as large‐area adsorbents extraction. resulting rGO@cellulose exhibits excellent extraction capacity, achieving 20 36.3 at 25°C 60°C, respectively, which translates gravimetric capacities...

Abstract Angularly fused carbocyclic frameworks and their heteroatom‐substituted analogues exist in many natural products that display a broad interesting range of biological activities. Preparation polycyclic by cycloaddition reactions have been the long‐standing hot topic synthetic community. Dehydro‐Diels–Alder (DDA) are one class dehydropericyclic derived conceptually systematic removal hydrogen atom pairs. A base‐promoted tandem Michael addition DDA reaction α,α‐dicyanoolefins with...
Methane seeping induced by natural gas hydrate dissociation is ubiquitous in deep-sea environment, which influences the global methane and carbon budget. Nevertheless, phase equilibrium characteristics that control stability of formation during bubble ebullition process in-situ multi-component environment remain unclear. "Haima" cold seep a typical active associated with abundant hydrate, necessitates unveiling potential formation. This work investigated conditions based on water depth...
Aluminum alloys with low density and high specific strength have been widely used in marine engineering. Epoxy coatings, a simple economical protection strategy, applied on alloy surfaces to prolong service life. However, pure epoxy coating cannot provide long-term for metals the environment. Hence, this work, nano-alumina (nano-Al2O3) modified by polyethyleneimine (PEI) were added into coatings enhance anticorrosion properties. Using Fourier transform infrared spectroscopy (FTIR), we found...

Nanozymes have been developed as new generation of biomimetic antibiotics against wound infection. However, most new-developed nanozymes based on inorganic particles or hybrid ones usually originate from incompatible raw materials unwanted metal salts, highly limiting their further biomedical usages. To overcome above drawbacks, it is required to develop novel with great antibacterial activity by using biocompatible reagents and endogenous species materials. Here, we demonstrated that bovine...
