Series　of　WO3/ZrO2　solid　acid　catalysts　with　hierarchically　porous　structure　were　prepared　by　the　one-pot　hydrothermal　method　involving　templating　from　a　composite　surfactant.　The　effect　of　calcination　temperatures　of　the　prepared　catalysts　on　the　acid　strength　was　studied　as　well　as　the　total　amount　of　acidity.　The　reaction　of　benzene　alkylation　with　1-dodecene　was　chosen　as　model　acid　catalysis.　The　results　indicated　that　the　acid　strength　and　the　total　amount　of　acidity　of　the　prepared　catalysts　increased　with　increasing　of　surface　area　and　crystallization　of　t-ZrO2.　Such　catalyst　shows　a　strong　catalytic　activity　of　the　alkylation,　and　both　the　alkylation　conversion　and　selectivity　increase　with　acid　strength.　Herein,　the　catalyst　sample　calcined　at　450°C　for　5　h　has　the　highest　catalytic　activity　and　selectivity.
