“…5,5-Dimethyl-1-pyrrolidine- N -oxide (DMPO) was used as a free radical trapping agent to detect ˙OH and ˙O 2 − . 35,36 As shown in Fig. 10, obvious ESR signals of DMPO−˙OH and DMPO−˙O 2 − were detected under light conditions, while they were not detected under dark conditions, indicating that oxidative TiO 2 only produces ˙OH and ˙O 2 − under light illumination.…”

“…The radius of semicircular arc in the Nyquist plot reflects the charge transfer resistance at the interface of electrode/electrolyte, wherein a smaller radius of Ag/α‐Fe 2 O 3 ‐5 electrode shows the lower resistance, hence lower recombination possibility of photogenerated electron–hole pairs compared with original α‐Fe 2 O 3 , suggesting the more favorable trend in photocatalytic reaction. [ 42–44 ] To identify the role of Ag species as a co‐catalyst, linear sweep voltammetry measurements are carried out for two samples (Figure 7d). The values of the overpotential to drive H 2 production are 0.62 and 0.54 V at a cathodic current density of 10 mA/cm 2 for original α‐Fe 2 O 3 and Ag/α‐Fe 2 O 3 ‐5 samples, respectively.…”

The ultrasmall Ag species decorated on α‐Fe2O3 nanorods photocatalysts are prepared through a facile in situ photodeposition process. The obtained Ag/α‐Fe2O3 composite samples display more outstanding photocatalytic activity than original α‐Fe2O3 in the degradation of tetracycline hydrochloride (TC‐HCl) in water. The degradation rate constant of TC‐HCl over the Ag/α‐Fe2O3‐5 sample reaches up to 0.0118 min−1, which is about 6.21 times than that over original α‐Fe2O3 sample (0.0019 min−1). The structure characterizations, physicochemical properties, and photoelectrochemical measurements reveal that the visible light absorption ability and charge separation efficiency are improved dramatically owing to the decoration effect of ultrasmall Ag species on the surface of α‐Fe2O3 nanorods. The photocatalytic reaction mechanism investigations demonstrate that holes, ˙O2−, and ˙OH all are main active species and play important roles in the degradation process of TC‐HCl.

A series of aryl sulfonic acids were tested as catalysts for acid hydrolysis occurring at the surface of poly(ethylene) terephthalate (PET) particles. Specifically, p‐toluenesulfonic acid monohydrate (PTSA), 2‐naphthalenesulfonic acid (2‐NSA), and 1,5‐naphthalenedisulfonic acid tetrahydrate (1,5‐NDSA) were chosen to provide sulfonic acid active groups and varying hydrophobic functionality. The effect of catalyst concentration and reaction temperature on PET hydrolysis rate was studied. The aryl sulfonic acid catalysts exhibited much higher rates of PET hydrolysis than the mineral acid, H2SO4. At 150°C and 4 M catalyst, the time required to achieve more than 90% TPA yield was 3, 3, and 8 h, and 18 h for (PTSA), (2‐NSA), (1,5‐NDSA), and H2SO4, respectively. Ethyl acetate hydrolysis was performed as a model reaction to probe the activity of the catalysts in homogenous reactions to compare with the heterogenous hydrolysis reaction occurring at the PET surface. The higher catalytic activities for PET hydrolysis of the PTSA, 2‐NSA, and 1,5‐NDSA than H2SO4 was attributed to improved wetting by the reaction media and affinity of the aryl sulfonic acid catalysts for the PET surface.
