The importance of porous carbon as the support material is well recognized in the catalysis community, and it would be even more attractive if several characteristics are considered, such as the stability in acidic and basic media or the ease of noble metal recovery through complete burn off. Because it is still difficult to obtain constant propert...

Lanthanum-transition-metal perovskites with robust meso-scale porous frameworks (meso-LaMO3) are synthesized through the use of ionic liquids. The resultant samples demonstrate a rather high activity for CO oxidation, by taking advantage of unique nanostructure-derived benefits. This synthesis strategy opens up a new opportunity for preparing functional mesoporous complex oxides of various compositions.


Tailoring the atomic structural configuration at metal and oxide interface offers an effective route for the development of catalysts with optimized properties. Here, we report the design of a unique structural configuration of yolk-shell-like FePt-FeOx nanoparticles (NPs), that exhibits notably enhanced activity and stability towards CO oxidation...
To further enhance catalytic activity and durability of nanocatalysts for oxygen reduction reaction (ORR), we synthesized a new class of 20 nm × 2 nm ternary alloy FePtM (M = Cu, Ni) nanorods (NRs) with controlled compositions. Supported on carbon support and treated with acetic acid as well as electrochemical etching, these FePtM NRs were converte...
SHANDONG, East China — The unmistakable wail of the suona pierces the dusk in the village as Wang Ruiyong plays a traditional tune on the double-reed instrument. The elderly funeral attendees approve, recognizing the melody. Yet for nearly five years now, Wang and other suona masters have been recording their repertoire in the fear that the songs could soon be forgotten as their tradition increasingly comes under threat.
Silicon (Si) has been regarded as next-generation anode for high-energy lithium-ion batteries (LIBs) due to its high Li storage capacity (4200 mA h g−1). However, the mechanical degradation and resultant capacity fade critically hinder its practical application. In this regard, we demonstrate that nanocoating of Si spheres with a 3 nm titanium diox...
The stabilization of surfactant-assisted synthesized colloidal noble metal nanoparticles (NPs, such as Au NPs) on solids is a promising strategy for preparing supported nanocatalysts for heterogeneous catalysis because of their uniform particle sizes, controllable shapes, and tunable compositions. However, surfactant removal to obtain clean surface...
Taming interfacial electronic effects on Pt nanoparticles modulated by their concomitants has emerged as an intriguing approach to optimize Pt catalytic performance. Here, we report Pt nanoparticles assembled on vacancy-abundant hexagonal boron nitride nanosheets and their use as a model catalyst to embrace an interfacial electronic effect on Pt in...
A simple, solvent-free, solid-state self-assembly strategy for the synthesis of alkaline-metal-oxide-doped mesoporous carbons (MCs) with tunable mesopores (~5-9 nm), high surface-areas (up to 571 m2/g) and large pore volumes (up to 0.65 cm3/g) is developed via the mechanochemical assembly between polyphenol-Ca2+/Mg2+ composites and F127 copolymers....

Though it has banned the suona from funerals, the local government has also paradoxically launched several initiatives to preserve the suona tradition. Since 2014, it has funded research and documentation of suona music, as well as an intangible cultural heritage protection plan that pairs around 15 masters with students. It also offers suona musicians performance opportunities. But according to Liu, the gigs are too few and too poorly compensated — some only pay 800 to 1,000 yuan ($120 to $150) for an eight-person band. He doesn’t believe that a state-sponsored imitation of the master-apprentice method will be able to sustain the tradition.

SHANDONG, East China — The unmistakable wail of the suona pierces the dusk in the village as Wang Ruiyong plays a traditional tune on the double-reed instrument.

Yet some young villagers share the government’s objections to suona funeral performances. To 27-year-old Dong Chengcheng, the funeral reforms are a positive step toward easing the burden on younger generations. “Although the price for booking a suona band is not such a big deal, it still costs money,” he explains. With each funeral typically requiring three days of ceremonies and banquets, the expenses add up — especially as family planning policies have left today’s young people with fewer siblings to share the costs.
