HZSM-5-supported phosphotungstic acid (PW) has been prepared and characterized. The results indicate that 5 wt% PW/HZSM-5 calcined at 773 K has the largest surface area and high dispersion of PW. It was confirmed that Keggin units are present inside the catalyst and that the proton of PW and the silanol of HZSM-5 interact via bridging structure. The catalytic properties of PW/HZSM-5 in the regioselective nitration of naphthalene to dinitronaphthalene were investigated. The best results, i.e. 48.5 % yield of 1,5-dinitronaphthalene, 49.2 % yield of 1,8-dinitronaphthalene, and the highest ratio of 1,5-dinitronaphthalene to 1,8-dinitronaphthalene, were obtained by use of 5 wt% PW/HZSM-5.
