“…In both samples, nanofibers were uniform, continuous, and randomly oriented ( Figure S1a,b ). This confirmed that the introduction of nitrogen did not change TiO 2 shape, in good agreement with the literature [ 22 , 25 , 34 ].…”

In this study, we combined electrospinning of a large amount of halloysite (HNT, 95%) with nitriding to produce N-HNT-TiO2 composite nanofibers (N-H95T5 hereafter) to be used for acetaminophen (ACT) photodegradation. Investigation of the morphological and structural properties of the obtained materials did not highlight any significant difference in their morphological features and confirmed that nitrogen was evenly distributed in the samples. Photocatalytic tests under visible light showed that acetaminophen photodegraded faster in the presence of samples with nitrogen (N-H95T5) than without (H95T5 nanofibers). Moreover, the N-H95T5 nanocomposite photocatalytic activity did not change after repeated utilization (five cycles). The addition of scavengers during photocatalytic tests showed the key implication of OH•−, O2•− and h+ radicals in acetaminophen degradation. These results indicated that N–H95T5 composite nanofibers could be considered a cheap multifunctional material for photodegradation and could open new prospects for preparing tunable photocatalysts.

“…PCM degradation was reduced to 20% when methanol (a scavenger for ·OH and ˙SO 4− ) 82 was used, and to 2% with p -benzoquinone (a scavenger of ˙O 2 − ). 52 This suggests that ˙O 2 − radicals play a key role in PCM degradation in the presence of PMS. Overall, this study revealed that ˙SO 4 − and ˙O 2 − radicals were the main reactive species, whereas ·OH radicals were only a minor species in PCM degradation.…”

“…PCM concentration in the different aliquots was determined by high-performance liquid chromatography (HPLC) coupled with mass spectrometry (MS) as previously described in ref. 22 and 52. PCM elimination efficiency was then determined using the HPLC-MS data and eqn (1): 53 where C 0 (mg L −1 ) is the PCM concentration at time = 0, and C (mg L −1 ) is the PCM concentration in the solution at the different time-points during electrocatalysis.…”

“…The ALD technology has become one of the important strategies for the manufacture of semiconductor photocatalysts, and ALD-based photocatalysts (e.g., TiO 2 , ZnO, g-C 3 N 4 , and their composites) [82,[110][111][112] are widely used to purify organic dyes, nutrients, antibiotics, and heavy metals in wastewater under UV or visible light irradiation. In addition, the ALD-based photocatalyst system has the advantages of large-scale preparation mode, strong light absorption capacity, stable chemical properties, and low price.…”

The precise design and efficient development of nanoscale materials at the atomic level has enabled high‐end renewable energy storage, conversion devices, and large‐scale environmental governance equipment. Atomic layer deposition (ALD) is a new vapor‐phase technology for precise surface thin‐film preparation, and is outstanding with self‐limiting reactions, large deposition area, adjustable film composition, film uniformity, angstrom thickness control and low temperature. With these characteristics, ALD plays an important role in many industry and research fields. This review briefly introduces the principle, main technical advantages and applications of ALD, including high‐k gate dielectrics, solar cells, fuel cells, and photocatalysis. The progress of the ALD technology in preparation and application of photocatalyst is emphatically reviewed, and the large‐scale application of ALD in photocatalytic thin‐film materials is prospected.This article is protected by copyright.
