基于LEAP模型的城市交通低碳发展路径研究——以广州市为例

open access: yes, 2019
以广州市为例,应用长期能源替代规划系统(LEAP)模型,通过设置政策情景、低碳情景和绿色低碳情景,模拟不同发展情景下广州交通领域未来的能源消费需求和CO2排放趋势,分析城市低碳发展的方向和路径。结果显示,随着城镇化进程的加快和生产生活运输需求的增加,广州交通领域碳排放总量将持续增长,但增长速度有所放缓。政策情景下,广州交通领域的CO2排放将于2035年左右达到峰值,严重滞后于广州市提出的碳排放总量达峰目标;低碳和绿色低碳情景下,通过加大低碳政策措施的力度,达峰时间有望分别提前到2025年和2023年 ...

广东货船水运的温室气体排放和低碳发展对策

open access: yes, 2013
作为我国港口大省和低碳试点省,广东需先行测算船舶水运的GHG(温室气体)排放量基线,以探究低碳水运对策. 通过文献调研收集适用数据和资料,基于引擎功率法,测算了广东抵港货船在2010年的GHG排放量. 结果表明:广东专属经济区海域内货船水运的GHG总排放量为2887×10~4t,不确定性在-36%~45%之间,其中在领海区域内的排放量为730×10~4t;远洋集装箱船是GHG最大排放源,占总排放量的43%;集装箱船、干散货船、油轮和其他货船的GHG排放量不确定性均介于-30%~50%之间 ...

Dual‐Phase Interpenetrating Reinforcement Enables an Ultrathin Sodium Metal Anode for High‐Energy‐Density Batteries

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Ultrathin sodium (Na) metal anodes (< 40 μm) with superior electrochemical performance are essential in developing high‐energy‐density sodium metal batteries (SMBs). Nonetheless, Metallic Na's poor processability hinders its practical application.

Breaking Shuttle‐Induced Kinetics Limitations in Lithium–Sulfur Batteries: Confined FeS2 Nanocatalyst With Optimized d‐Band Center

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT The commercialization of lithium‐sulfur batteries (LSBs) faces dual challenges of sluggish sulfur redox kinetics and lithium polysulfides (LiPSs) shuttling. Herein, we demonstrate a synergistic strategy combining multidimensional structural confinement with d‐band center modulation to simultaneously suppress LiPSs diffusion and catalyze ...

Nitrogen–Doped Carbon Nanotube–Supported Ni3Se4–CeO2 Heterojunctions With Multi–Orbital Hybridization for Efficient Hydrogen Evolution Reaction

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Engineering of the catalyst interface and modulation of transition–metal d–band play critical roles in the electrocatalytic hydrogen evolution reaction (HER). Herein, a synthetic strategy is developed to fabricate nitrogen‐doped carbon nanotubes (N–CNTs)–supported Ni3Se4–CeO2 heterojunction catalysts through a facile chemical vapor deposition (

Phosphorus‐Doping Drives the Formation of a Pt‐Skin@PtFe Alloy Catalyst With Modulated d‐Band Center for Oxygen Reduction

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Platinum (Pt)‐based catalysts are crucial for the commercialization of hydrogen/metal air batteries, but they suffer from Pt scarcity, high cost, and nanoparticle dissolution/agglomeration, mainly leading to performance degradation. We address this by synthesizing a PtFe alloy catalyst (PtFe–PA–NC) via a phytic acid (PA) assisted pyrolysis ...

Size‐Dependent Hydrogen Dissociation Capacity in Ni/CeO2 Catalysts for Low‐Temperature CO2 Methanation

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Converting CO2 to CH4 under mild conditions is a promising strategy for solving environmental and energy problems, but also a challenge. In this work, the low‐temperature CO2 hydrogenation process over Ni/CeO2 catalysts was significantly accelerated by optimizing the H2 dissociation ability of Ni through the size effect, thus A‐Ni/CeO2 with an
