PPy-SbW9-TM-SnR/Pt-based electrocatalysts were prepared by the electro-deposition method and showed good performance for the methanol oxidation reaction.

The development of acid-resistant and efficient corrosion inhibitors is of great significance for metal protection in many industrial processes. In this work, eight cases of sandwichtype polyoxometalate (POM)-based inorganic−organic hybrids, namely, carboxyethyltin and transition metal (TM) cofunctionalized tungstoantimonates and tungstobismuthates, formulated as Na x K 10−x [(SnR) 2 (TM(H 2 O) 3 ) 2 (B-β-SbW 9 O 33 ) 2 ]•mH 2 O and Na y K 10−y [(SnR) 2 (TM(H 2 O) 3 ) 2 (B-β-BiW 9 O 33 ) 2 ]•nH 2 O (abbreviated as SbW 9 -TM-SnR and BiW 9 -TM-SnR;
