While spherical (AuNS) observed in presence 30-mer poly T, like that absence DNA, A or C induces formation flower-shaped nanoparticle (AuNF). Detailed mechanistic studies indicate difference affinity to AuNP plays a major role control processes. adsorbed AuNS surface could act as template mediate flower-like nanoparticles. AuNF can result from either selective deposition...
Recently, ultrathin 2D photocatalysts have attracted people's attention due to their performances in the area of solar energy conversion. However, synthesis with a nonlayered crystal structure is still full challenges. Herein, BiVO4 nanosheets (NSs) monoclinic are synthesized through convenient colloidal two-phase method. The as-prepared NSs possess thickness less than 3 nm but diameter larger 1.2 μm. Furthermore, presence HNO3 facilitates growth nearly naked surfaces, largely exposed {010}...
As a family of semiconductor photocatalysts, Sillén-type bismuth oxyhalides (BiOX, X = Cl, Br, I) have attracted widespread interest due to their excellent photocatalytic activity and photoconductivity. However, most current strategies on synthesizing ultrathin 2D BiOX nanosheets (NSs) rely high temperature pressure complex procedures, which seriously confine large-scale applications. Herein, we develop simple facile two-phase method for the synthesis NSs with highly exposed {001} facets. On...
Abstract Systematically controlling the morphology of nanoparticles, especially those growing from gold nanorod (AuNR) seeds, are underexplored; however, AuNR and its related morphologies have shown promises in many applications.

Due to their high specific capacity and long cycle life, bimetallic sulfides are the preferred choice of researchers as anodes in sodium-ion batteries (SIBs). However, studies indicate that this class materials often requires expensive elements such Co, Sb, Sn, etc., performance is insufficient with use inexpensive Fe, V alone. Therefore, there a need explore relationship between metal cations anode so requirements cost reduction enhancement can be met simultaneously. In work, series...
Abstract Binary metal sulfides hold significant promise as anode materials for advanced sodium‐ion batteries (SIBs), but their application is often limited by rapid capacity degradation and slow reaction kinetics.
