Interconnected surface-vacancy-rich PtFe nanowires for efficient oxygen reduction

Abstract: Catalysts that boost the oxygen reduction reaction (ORR) are highly needed for fuel cells and metal–air batteries. Herein, we report the preparation of surface-vacancy-rich PtFe interconnected nanowires as an excellent ORR catalyst. When utilized in both alkaline and acidic electrolytes, this hierarchically structured catalyst shows high mass activities at 0.9 V versus the reversible hydrogen electrode (RHE) (alkaline electrolyte: 3.65 A mgPt−1 and acid: 1.10 A mgPt−1), high half-wave potential (alkaline electrolyte: 0.959 V vs. RHE and acid electrolyte: 0.924 V vs. RHE), and high stability (almost no activity loss after 10 000-cycle accelerated durability testing). Density functional theory calculations reveal that the presence of vacancies on the Pt-skin provides rich active ORR sites that can weaken the bonding strength and adsorption of O-containing intermediates. This paper presents a facile strategy to assemble efficient hierarchically structured electrocatalysts with rich surface defects for devices such as fuel cells.

On a Li–Stević integral-type operator from Bloch-type spaces into logarithmic Bloch spaces

Abstract: Let ϕ be an analytic self-map of the unit disk 𝔻, H(𝔻) the space of analytic functions on 𝔻 and g∈H(𝔻). Recently Li and Stevic defined the following operator on H(𝔻). The boundedness and compactness of the operator from the Bloch-type spaces into the logarithmic Bloch spaces are investigated in this paper.

Do foreign direct investment and environmental regulation improve green technology innovation? An empirical analysis based on panel data from the Chinese manufacturing industry

Abstract: The environmental regulation and foreign direct investment (FDI) inflow have an important impact on the progress of green technology. This study analyzes the impacts of environmental regulation and FDI on green technology innovation (GTI) based on the panel data of 13 Chinese manufacturing sectors. The results of static panel regression show that the environmental regulation has a positive impact on GTI, while the FDI has a negative impact. The results of the panel threshold model reveal that the effect of environmental regulation on GTI presents a nonlinear shape. The negative effect of FDI on GTI is strengthened when the environmental regulation exceeds its threshold. Increasing FDI inflow can inhibit the effect of environmental regulation. Meanwhile, a strict environmental regulation can enhance the inhibiting effect of FDI on GTI. The FDI inflow into high-tech manufacturing sectors has a less negative impact on GTI than the FDI inflow into low-tech sectors in the case of the enhancement of environmental regulation. This study provides some implications for the formulation of environmental regulation and the FDI inflow into China to improve the GTI.
