Ordered mesoporous materials have received great attention due to their well-defined pore structures and potential applications in catalysis, adsorption, separation, drug delivery, etc. Although various compositions of mesoporous solids have been successfully prepared, the preparation of crystalline non-metallic oxyacid salts with ordered mesoporosity remains a major challenge. Herein, we report the synthesis of a mesoporous solid acid crystalline boron phosphate（BPO4） catalyst with a bicontinuous shifted double diamond（SDD） hyperbolic surface structure. The BPO4scaffold was obtained by synergistic selfassembly in a mixed solvent of water and tetrahydrofuran using the diblock copolymer poly（ethylene oxide）-block-polystyrene as template and phosphoric acid and orthoboric acid as inorganic sources. The structure consists of two sets of diamond networks adjacent to each other with a mesostructural scale tetragonal symmetry（space group I41/amd） with unit cell parameters of a =80 nm and c = 113 nm, which affords the scaffold a specific surface area of 44 m2/g. As a solid acid catalytic material, the SDD BPO4scaffold exhibited excellent catalytic activity at room temperature with a conversion of furfural to 2-（dimethoxymethyl）furan over 70% and can be reused after recovery without serious loss of activity. In the propane oxidative dehydrogenation reaction, SDD BPO4demonstrated high olefin productivity and selectivity while maintaining high reaction rate. This study provides ideas for the preparation of ordered mesoporous crystalline catalytic materials and demonstrates their potential for practical applications.

In the current information society, the dissemination mechanisms and evolution laws of individual or collective opinions and their behaviors are the research hot topics in the field of opinion dynamics. First, in this paper, a two-layer network consisting of an individual-opinion layer and a collective-opinion layer is constructed, and a dissemination model of opinions incorporating higher-order interactions(i.e. OIHOI dissemination model) is proposed. Furthermore, the dynamic equations of opinion dissemination for both individuals and groups are presented. Using Lyapunov's first method,two equilibrium points, including the negative consensus point and positive consensus point, and the dynamic equations obtained for opinion dissemination, are analyzed theoretically. In addition, for individual opinions and collective opinions,some conditions for reaching negative consensus and positive consensus as well as the theoretical expression for the dissemination threshold are put forward. Numerical simulations are carried to verify the feasibility and effectiveness of the proposed theoretical results, as well as the influence of the intra-structure, inter-connections, and higher-order interactions on the dissemination and evolution of individual opinions. The main results are as follows.(i) When the intra-structure of the collective-opinion layer meets certain characteristics, then a negative or positive consensus is easier to reach for individuals.(ii) Both negative consensus and positive consensus perform best in mixed type of inter-connections in the two-layer network.(iii) Higher-order interactions can quickly eliminate differences in individual opinions, thereby enabling individuals to reach consensus faster.
