| 摘要 | The fabrication of a photocatalytic air-purifying pavement with a facile loading route, long depolluting period, and excellent deNO(x) activity under weak solar irradiation is essential for ambient air purification. Herein, a promising methodology is developed relying on the exploitation of a graphitic carbon nitride/TiO2 (g-C3N4/TiO2) composite hydrosol at room temperature. The TiO2 hydrosol can act as a source of photocatalyst and dispersant for g-C3N4 during loading. The photoinduced hydrophilicity, adhesive force, and regeneration tests in the laboratory show the long-term deNO(x) application potential of g-C3N4/TiO2 coatings. Field studies indicate that the NO removal rate is 70.7% of g-C3N4/TiO2-coated pavement in the morning (07:00-10:00) and afternoon (17:00-19:00), at which times solar radiation is weakest. The deNO(x) efficiency is influenced by solar irradiation and traffic volume. The latter exerts a more significant influence on deNO(x) efficiency than the former. A desirable route in fabricating a photocatalytic air-purifying pavement is provided and offers a promising photocatalyst suitable for outdoor environmental remediation. |
