Abstract:In the present study, a nanocomposite material g-C 3 N 4 /Fe-TiO 2 has been prepared successfully by a simple one-step hydrothermal process and its structural properties were thoroughly studied by various characterization techniques, such as X-ray diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy, electron paramagnetic resonance (EPR) spectrum, X-ray photoelectron spectroscopy (XPS), and UV-vis diffuse reflectance spectrometry (UV-vis DRS). The performance of the fabricated composite material towards the removal of phenol from aqueous phase was systematically evaluated by a photocatalytic approach and found to be highly dependent on the content of Fe 3+ . The optimum concentration of Fe 3+ doping that showed a dramatic enhancement in the photocatalytic activity of the composite under visible light irradiation was observed to be 0.05% by weight. The separation mechanism of photogenerated electrons and holes of the g-C 3 N 4 /Fe-TiO 2 photocatalysts was established by a photoluminescence technique in which the reactive species generated during the photocatalytic treatment process was quantified. The enhanced photocatalytic performance observed for g-C 3 N 4 -Fe/TiO 2 was ascribed to a cumulative impact of both g-C 3 N 4 and Fe that extended its spectrum-absorptive nature into the visible region. The heterojunction formation in the fabricated photocatalysts not only facilitated the separation of the photogenerated charge carriers but also retained its strong oxidation and reduction ability.

With the continuous development of network information technology, the process of social informatization is further accelerated, information transmission and exchange between different regions is more convenient, and people’s demand for information is further met. At the same time, with the continuous advancement of media technology, new media has gradually emerged, becoming the main force of social media and playing an important role in people’s daily lives. The purpose of this article is to study the interaction between artificial intelligence and new media based on social information. This article explains the meaning of new media from the narrow and broad perspectives, and introduces the characteristics of new media; then the interaction between new media based on artificial intelligence and social informatization is studied from both positive and negative effects. In the experimental part, this paper adopts the questionnaire method and uses 472 valid questionnaires as the data basis to count the respondents’ awareness of the interaction between new media based on artificial intelligence and social information. The statistical result is that only 31.8% think that the degree of mutual influence is very deep. This article also puts forward suggestions to promote the mutual development of new media based on artificial intelligence and social informatization.
