Atomically thin platinum shells on gold nanoparticles (NPs) are synthesized in one pot under mild conditions. The core-shell NPs exhibit excellent catalysis for energy related processes such as electrochemical oxidation of biofuels, aromatic ring hydrogenation, and γ-valerolactone production.

Polyvinyl pyrrolidone-stabilized Rh nanoparticles (RhNPs/PVP) of ca. 2.2 nm in size were prepared by the hydrogenation of an organometallic complex [Rh(η 3 -C 3 H 5 ) 3 ] in the presence of PVP and evaluated as a catalyst in the hydrogenation of a series of arene substrates as well as levulinic acid and methyl levulinate Q3 .Please check this proof carefully. Our staff will not read it in detail after you have returned it.Translation errors between word-processor files and typesetting systems can occur so the whole proof needs to be read. Please pay particular attention to: tabulated material; equations; numerical data; figures and graphics; and references.

Please e-mail a list of corrections or the PDF with electronic notes attached -do not change the text within the PDF file or send a revised manuscript. Corrections at this stage should be minor and not involve extensive changes. All corrections must be sent at the same time.Please bear in mind that minor layout improvements, e.g. in line breaking, table widths and graphic placement, are routinely applied to the final version.We will publish articles on the web as soon as possible after receiving your corrections; no late corrections will be made.Please return your final corrections, where possible within 48 hours of receipt, by e-mail to: dalton@rsc.orgQueries for the attention of the authors
