摘要：The recent development of Cu-based electrocatalysts for electrochemical reduction of carbon dioxide（CO） has attracted much attention due to their unique activity and selectivity compared to other metal catalysts. Particularly, Cu is the unique electrocatalyst for COelectrochemical reduction with high selectivity to generate a variety of hydrocarbons. In this review, we mainly summarize the recent advances on the rational design of Cu nanostructures, the composition regulation of Cu-based alloys, and the exploitation of advanced supports for improving the catalytic activity and selectivity toward electrochemical reduction of CO. The special focus is to demonstrate how to enhance the activity and selectivity of Cubased electrocatalyst for COreduction. The perspectives and challenges for the development of Cu-based electrocatalysts are also addressed. We hope this review can provide timely and valuable insights into the design of advanced electrocatalytic materials for COelectrochemical reduction.

摘要：In this study,a copper ferrocyanide/silica/polyvinylidene fluoride(CuFC/SiO2/PVDF)hollow-fiber composite membrane was successfully synthesized through a facile and effective crosslinking *** PVDF hollow-fiber membrane with embedded SiO2 was used to fix the dispersion of CuFC nanoparticles for cesium(Cs)*** surface morphology and chemical composition of the composite membrane were analyzed using scanning electron microscopy and X-ray photoelectron spectroscopy(XPS).The composite membrane showed a high Cs rejection rate and membrane flux at the three layers of CuFC and 0.5%SiO2,and its Cs rejection rate was not affected by variation in the pH(pH=4–10).The modified membrane could be effectively regenerated many times using ammonium nitrate(NH4NO3).The Cs selectivity performance was verified by an efficient Cs rejection rate(76.25%and 88.67%in 8 h)in a solution of 100 lg L 1 of Cs with 1 mmol L 1 of competing cations(K+and Na+).The CuFC/SiO2/PVDF hollowfiber composite membrane showed a particularly superior removal performance(greater than 90%)in natural surface water and simulated water with a low Cs ***,the CuFC/SiO2/PVDF hollow-fiber composite membrane can be used directly in engineering applications for the remediation of radioactive Cs-contaminated water.

摘要：Drug delivery systems(DDSs) have been getting more and more attention in the field of cancer therapy with the development of nanotechnology. But remote and noninvasive controlled drug release for improving treatment efficacy and reducing side effects faces great challenge. We report a kind of 'smart' nanocomposites(NCs) that is sensitive to the surrounding temperature by grafting a layer of thermosensitive polymer, poly(N-isopropylacrylamide)(pNIPAm),on the surface of single Cu_7S_4 nanoparticle(NP) via atomtransfer radical polymerization(ATRP). These NCs demonstrate a photothermal conversion efficiency of 25.4% under808-nmnear infrared(NIR) light irradiation and a drug loading content of 19.4%(drug/total NCs, w/w) with a lower critical solution temperature(LCST) of ~38°C. At normal physiological temperature(37°C), only 10.8% of the loaded doxorubicin(DOX) was released at physiological pH value(pH7.4) within 10 h. In the presence of 808-nm irradiation, due to the temperature increment as a result of photothermal effects,DOX was rapidly released.
