Ultrathin two-dimensional （2D） nanomaterials offer unique advantages compared to their counterparts in other dimensionalities. O-vacancies in such materials allow rapid electron diffusion. Carbon doping often improves the electric conductivity. Considering these merits, the WO3-x/C ultrathin 2D nanomaterial is expected to exhibit excellent electrochemical performance in Li-ion batteries. Here, ultrathin WO3-xC nanosheets were prepared via an acid-assisted one-pot process. The as-prepared WO3-x/C ultrathin nanosheets showed good electrochemical performance, with an initial discharge capacity of 1,866 mA·h·g^-1 at a current density of 200 mA·g^-1 After 100 cycles, the discharge and charge capacities were 662 and 661 mA·h·g^-1, respectively. The reversible capacity of the WO3-x/C ultrathin nanosheets exceeded those of WO3 and WOg-x nanosheets. The electrochemical testing results demonstrated that WO3-x/C ultrathin nanosheets are promising alternative anode materials for Li-ion batteries.

The development of low cost, metal free semiconductor photocatalysts for CO2 reduction to fuels and valuable chemical feedstocks is a practically imperative for reducing anthropogenic CO2 emissions. In this work, black phosphorus quantum dots（BPQDs） were successfully dispersed on a graphitic carbon nitride（g-C3N4） support via a simple electrostatic attraction approach, and the activities of BP@g-C3N4 composites were evaluated for photocatalytic CO2 reduction. The BP@g-C3N4 composites displayed improved carrier separation efficiency and higher activities for photocatalytic CO2 reduction to CO（6.54 μmol g^-1h^-1 at the optimum BPQDs loading of 1 wt%） compared with pure g-C3N4（2.65 μmol g^-1h^-1）. This work thus identifies a novel approach towards metal free photocatalysts for CO2 photoreduction.

随着世界工业化和城市化水平的提高,人类可直接利用的淡水资源日益减少,对淡水资源的需求急剧增加,淡水的制备和净化技术愈发重要。太阳能海水淡化技术可将无穷无尽的太阳能转变成热量,加热蒸发海水使其变成蒸汽,蒸汽冷凝制得淡水,是一种具备广阔前景的解决淡水短缺问题的技术。然而,太阳能海水淡化一直受到太阳能吸收材料成本高、效率低的限制。本工作设计并制备一种新型复合水凝胶,该复合水凝胶由太阳光吸收体(碳材料)和天然高分子(甲壳素)组成,增加太阳光利用,提高海水淡化效率,最高可达75%。在1 kW/m^(2)太阳光照下,其蒸发速率超过1.5 kg/(m^(2)·h),蒸汽效率最高为98.34%。而且该复合水凝胶具有成本低、结构多孔、制造工艺简单、可回收性强、机械稳定性好等优点。因此,碳材料/甲壳素复合水凝胶作为太阳光吸收体具有将光能转化为热能的潜力,为海水淡化开辟了新的途径。
