By using literature data and dialectical analysis methods, this paper elaborates on the value and path of promoting students physical and moral education through the personality of a gentleman in the perspective of core literacy. The value reflected is that the physical and moral character of sports, characterized by love, aspiration, faith, and righteousness, inherits and develops the gentleman personality centered on the traits of benevolence, righteousness, courtesy, wisdom, faithfulness, loyalty, courage, self-improvement, harmony without uniformity, and cultural refinement in a way that is complementary, mutually reinforcing, and mutually educating, embodying the coexistence of civilized spirit and savage physique, and practicing the development concept of integrating sports and education. It is a manifestation of the transformation from preaching morality to incarnating morality, the implementation of the goal of moral education, and the integration of traditional culture and sports spirit, which enhances the humanistic quality of sports disciplines. In the process of promoting the integration of the personality of a gentleman and the physical and moral character of sports, attention should be paid to guiding the demonstration from verbal teaching to setting an example through personal conduct, highlighting the radiating value from respecting the small to knowing the big, and emphasizing the overall practice from in-class to out-of-class, in order to guide students to demonstrate both their sportsmanship and their moral integrity, and to truly achieve the coexistence and development of savage physique and civilized spirit.

Supported Pt─Au bimetal nanocatalysts have been prepared by an in situ reduction method followed by calcination in air and reduction in H2 atmosphere. The catalysts exhibit a typical yolk-shell construction composed of a moveable magnetic Fe core and metal oxides shells decorated with Pt─Au nanoparticles. The structure of the bimetal nanocatalysts was characterized in detail by TEM, XRD, XPS, and N2 physical adsorption and the catalytic activity of the nanocatalysts was studied by the catalytic reduction of 4-nitrophenol to 4-nitrophenol. It is found that the bimetal nanocatalysts composed with the different metallic oxides (TiO2 and ZrO2) exhibited the comparable Pt─Au particles size (~10 nm). However, the content of Pt─Au nanoparticles was varied with the metallic oxides support. Pt─Au nanoparticles deposited uniformly on TiO2 with higher loadings, however the nanoparticles on ZrO2 exhibited remarkably lower content, which should be attributed to the abundant hydroxyl on TiO2 surface that served as the deposition site for Pt─Au nanoparticles. The result of the reduction reaction indicated that incorporation of TiO2 in the bimetal Pt─Au nanocatalyst could significantly improve the catalytic activity as compared with ZrO2 and m-SiO2. A possible mechanism was proposed to explain the synergistic effect in the supported Pt─Au bimetal nanocatalysts.

Au-Pt alloy nanoparticles that are selectively anchored on TiO2 surface of the ellipsoidal zirconium titanium composite oxides were successfully prepared by a facile two-step method: prefabricated binary composite oxides on the ellipsoidal Fe2O3@SiO2 by a versatile cooperative template-directed coating method, and then in situ formation of Au-Pt alloy NPs with Sn2+ as the reduction agent. The alloy catalysts were characterized by X-ray diffraction, transmission electron microscopy and X-ray photoelectron spectroscopy. The result suggested that highly dispersive and ultrafine Au-Pt alloy nanoparticles were deposited onto TiO2 surface of the binary oxides solely. The particle size of nanoalloys was closely related to the ratio of Zr : Ti in the composite oxides shell. Increasing the content of Zr element led to a growth in the size of alloy nanoparticles. When used as catalysts for the reduction of 4-nitrophenol, the prepared supported alloyed catalysts exhibited high catalytic activity, and the sample could be easily recycled without a significant decrease of the catalytic activity.
