Exceedingly high photocatalytic activity of g-C 3 N 4 /Gd-N-TiO 2 composite with nanoscale heterojunctions

New BiOXs/TiO 2 heterojunction photocatalyst towards efficient degradation of organic pollutants under visible‐light irradiation

“…4 b , d and f ), the absorption band intensities of organic pollutants always decrease with the increasing of irradiation time, implying the organic pollutants could be effectively degraded during the photo illumination process. In addition, compared with other reported TiO 2 composite catalysts (Table 1), BiOXs/TiO 2 also displays excellent photocatalytic activity [20–28].…”

“…The photocatalytic degradation experiments indicate that BiOXs/TiO 2 can effectively decompose methyl orange (MO), bisphenol A (BPA) and tetracycline (TET) under the visible‐light illumination. Moreover, the degradation efficiency is superior to that of the TiO 2 composite materials in the reported literature [20–28].…”

Synthesis of 3D flower-like structured Gd/TiO2@rGO nanocomposites via a hydrothermal method with enhanced visible-light photocatalytic activity

“…The high adsorption amount in the initial step of the hysteresis loop corresponding to the capillary condensation of Gd inside the mesopores reveals a narrow pore-size distribution of the GTR materials. 39 The specic surface area, pore volume, and pore size of different samples were calculated, and the data are summarized in Table 1. For pure TiO 2 , GO@TiO 2 , 2% GTR, 3% GTR, and 4% GTR, the specic surface areas are determined as 49.0, 119.6, 122.7, 125.6, and 112.7 m 2 g À1 , the total pore volumes are 0.25, 0.31, 0.34, 0.35, and 0.37 cm 3 g À1 , and the pore sizes are 7.22, 4.61, 3.82, 3.84, and 4.32 nm, respectively.…”
