The electrochemical reduction of benzoic acid in the presence and absence of hydrogen ( H ( 2 ) ) has been investigated using a 10 mu m diameter platinum microelectrode in four different room temperature ionic liquids ( RTILs ) , namely [ C ( 4 ) mim ] [ NTf ( 2 ) ] , [ C ( 4 ) mpyrr ] [ NTf ( 2 ) ] , [ C ( 4 ) mim ] [ OTf ] and [ C ( 4 ) mim ] [ BF ( 4 ) ] , versus Ag / Ag ( + ) .
 Chemical: benzoic acid; Chemical: hydrogen; Chemical: H ( 2 ); Chemical: platinum; Chemical: [ C ( 4 ) mim ] [ NTf ( 2 ) ]; Chemical: [ C ( 4 ) mpyrr ] [ NTf ( 2 ) ]; Chemical: [ C ( 4 ) mim ] [ OTf ]; Chemical: [ C ( 4 ) mim ] [ BF ( 4 ) ]; Chemical: Ag; Chemical: Ag ( + )
