In this system, the preparation of high-quality photoanode is essential for achieving efficient solar hydrolysis. Polymeric carbon nitride has emerged as a promising photocatalyst for solar water splitting due to its visible light absorption, suitable band edge positions and good chemical stability. However, considerable difficulties have been encountered for the preparation of robust and well-bonded carbon nitride films on conductive substrates. Herein, a combined strategy of electrophoresis and vapor deposition results in robust and high performing carbon nitride film photoelectrodes with good bonding on substrates, suitable thickness for light absorption, and enhanced charge separation and transfer abilities. The unique structure of the photoanode thus facilitates the oxidation of water and leads to an optimal photocurrent density of approximately 120 μA cm-2 at 1.23 VRHE. This work provides new insights for the preparation of polymeric carbon nitride film photoelectrodes, promoting the developments of photoelectric and photoelectrochemical applications based on carbon nitride.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47045354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There were six different methods applied to six different types of OCFs. The antimicrobial performances demonstrate around 95.33% and 93.88% reduction of gram-positive and gram-negative bacteria after 30 times home laundry, respectively. The color stability yield by the surface plasmon resonance mates the commercial requirement in items of colorfastness ratings of 3-4 for wash, 4 for light, 4-5 for dry rubbing, and 3-4 for wet rubbing. These findings established that this treatment successfully endowed OCFs with long-lasting antimicrobial capabilities and thermal stability due to the interaction with the microparticles. The phenomenon was further confirmed by morphological, spectroscopical, and thermal characterization. This approach of OCFs functionalization avoiding hazardous chemicals could be a benchmark for antimicrobial performances in sustainable industrial applications.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41807507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results showed that surfaces of composite coatings possessed rough hierarchical micro/nanostructures, especially, the surface water contact angle is as high as 160° and the sliding angle is less than 2.1° when the ratio of PDMS/TiO2 was 1:5. In addition, through a series of high-temperature exposure, acid-alkali resistance, self-cleaning, and electrochemical corrosion tests, it was also found that the superhydrophobic surface with a PDMS/TiO2 ratio of 1:5 had excellent properties, and showed certain practicability in terms of anticorrosion, antipollution and durability.

But it typically suffers from nitrite accumulation due to the high selectivity towards nitrite formation. To address this issue, we herein report a strategy of modifying Cu nanowires with Ni nanoparticles to improve the NO3RR performance. The Ni nanoparticles both facilitate electron transfer from Ni to Cu and enhance the conversion of nitrite, thereby improving the overall removal of nitrate with a minimal yield of nitrite. Through a facile liquid phase deposition process, the loading amount of Ni nanoparticles can be easily tailored by simply changing the concentration of precursors, and the best Cu/Ni molar ratio for nitrate removal performance is 20. Under this ratio, the material simultaneously delivers a high nitrate removal rate of 92.2% and a low nitrite selectivity of only 2.2% at –0.9 V vs. reversible hydrogen electrode, accompanied with superior stability for a continuous NO3RR. This study thus offers an efficient, stable, and low-cost Cu-Ni bimetallic catalyst for NO3RR.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2022-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49160871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their structures and mass densities (0.28-1.35 g cm−3) were tunable by adjusting the content of polysiloxane precursor in impregnating solution. The lightweight CNFA/SiOC composite featured with continuous conductive network and highly porous structure in SiOC matrix, resulting in high specific shielding effectiveness (up to 68.9 dB·cm3 g−1 with SETotal of 19.3 dB) due to enhanced conductance loss and multi reflection/scattering.

Moreover, the CNFA/SiOC composite exhibits good oxidation resistance with SETotal retention of above 98% after heat treatment at 600°C for 2 h in air, which arises from the effective protection of CNFs by SiOC.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46429545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
