“…According to the previous reports (Cai et al, 2013;Gao et al, 2013b;Ma et al, 2011) and our experimental results (Fig. S1 in the Supplementary information), there was no doubt that urchin-like Au@PtNHs could catalyze the oxidation of TMB to produce blue color in the presence of H 2 O 2 , indicating that urchin-like Au@PtNHs indeed exhibited intrinsic peroxidase-like activity.…”

“…For example, in this specific reaction, it's relatively easy to synthesize Pt or alloys nanotubes (PtNTs) /porous NTs using TeNWs as template 6,26 . However, it is difficult to transfrom TeNWs to nano-branches Pt nanomaterials completely in general due to the limitation of 1D nanostructures 22 .…”

Dentritic Pt-based nanomaterials with enriched edge and corner atoms have recently attracted considerable attention as electrocatalysts. Meanwhile, Pt(111) facets are generally considered more active for the glycerol oxidation reaction (GOR). Thus, it is significant to construct the rational design and synthesis of dentritic Pt whose surface is mostly enclosed by {111} facets. Reported herein is a unique Pt-branched structure enriched by a large amount of valency unsaturated atoms prepared by the aggravation of the galvanic replacement strategy. The synthesis is developed to generate highly crystallized Pt nanoflowers using Te nanowires as a template. Furthermore, the electrochemical results show that Pt nanoflower is an excellent catalyst with higher mass activity and better structure stability than commercial Pt/C (20% Pt) for glycerol electro-oxidation. Besides, the template-broken approach could provide a novel potential way to synthesize Pt-based or other noble metals/alloys for their advanced functional applications.

A convenient method was developed for controllable synthesis of homogeneous trigonal Te/Se alloy nanorods (t-Te/Se ANRs) with diverse morphologies, aspect ratios and compositions at room temperature in aqueous solution. These alloy nanorods were formed by a self-seeding process. By varying the molar ratio of TeO 2 to H 2 SeO 3 ĲxĲTe : Se)) in the initial precursors, the morphology of t-Te/Se ANRs was transformed mainly via two paths: formation of tri-fold nanorods (TNRs) or single nanorods (SNRs). The nanostructures of TNRs were generated only by using xĲTe : Se) ranging from 30 : 1 to 10 : 1, and SNRs were formed using xĲTe : Se) ranging from 200 : 1 to 100 : 1 or 2 : 1 to 1 : 1. The microstructures, compositions, and growth mechanisms of these nanorods were also analyzed in detail. Experimental section MaterialsTellurium dioxide (TeO 2 , Aladdin, 99.99%), selenious acid ĲH 2 SeO 3 , Aladdin, 99.99%), sodium dodecyl sulfate (SDS, Aldrich, 99.99%) and hydrazine monohydrate ĲN 2 H 4 ĴH 2 O, Sinopharm, 85%, AR) were used as-purchased. 18 MΩ cm CrystEngComm, 2015, 17, 3243-3250 | 3243 This journal is
