dc.description.abstract | Photocatalytic sustainable fuel production attracted extensive attention because of the urgent need of the society to shift from fossil fuels to solar fuels. Herein, the synthesis of hexagonal rosettes of g-C3N4 with an efficient performance toward hydrogen evolution and hydrogen peroxide production as the two kinds of solar fuels were reported. The hexagonal rosettes of g-C3N4 were simply fabricated via controlled solid-state polymerization of three-dimensional hexagonal rosettes of cyanuric acid-melamine adduct at 500 degrees C. The hexagonal rosettes of g-C3N4 showed an amorphous nature with an extremely high surface area of 400 m(2) g(-1). Also, the as-obtained catalyst demonstrated remarkable photocatalytic activity in hydrogen production of 1285 mu mol g(-1) h(-1) and hydrogen peroxide production of 150 lmol g(-1) h(-1). The mechanism for the polymerization process of the cyanuric acid-melamine (CM) complex to hexagonal rosettes of g-C3N4 was thoroughly described employing electron microscopy tools. This study identified that the CM complex condensation is accomplished via a dehydration process by producing a highly condensed and active structure of g-C3N4, which is different from the previously reported condensation mechanism of the melamine and its derivatives performed through a deamination process.
