Tungsten　trioxide　has　attracted　extensive　attention　for　photocatalytic　applications　owing　to　its　unique　structure　and　intrinsic　merits;　however,　the　small　specific　surface　area　and　rapid　electron-hole　recombination　still　limit　its　adsorption　and　photocatalytic　efficiency.　Herein,　WO3　center　dot　0.33H(2)O/g-C3N4　nanocomposite　photocatalysts　were　designed　and　constructed　using　a　facile　low　temperature　hydrothermal　method.　The　interaction　between　1D　WO3　center　dot　0.33H(2)O　nanorods　and　2D　g-C3N4　nanosheets　produces　a　heterojunction　with　enhanced　adsorption　and　photocatalytic　degradation　performance　towards　methylene　blue　pollutant.　It　is　found　that　the　synergistic　effect　of　the　surface　charge　and　specific　surface　area　significantly　enhances　the　adsorption　capacity　which　can　be　up　to　23　times　higher　than　that　of　WO3　center　dot　0.33H(2)O,　and　the　optimal　photocatalytic　activity　is　3.67　and　1.70　times　higher　than　that　of　pristine　WO3　center　dot　0.33H(2)O　and　g-C3N4,　respectively.
