题目解答

答案

C. Research question.

解析

本题考查对科研论文标题信息的理解和推理能力。解题的关键在于分析标题中所包含的各个要素，然后判断每个选项是否能从标题中合理推断出来。

对标题的分析

标题 “Increasing Stability and Activity of Core - shell Catalysts by Preferential Segregation of Oxide on Edges and Vertices: Oxygen Reduction on Ti - Au@Pt/C” 可拆解为以下部分：

  • “Increasing Stability and Activity of Core - shell Catalysts” 表明了研究的目标，即提高核 - 壳催化剂的稳定性和活性。
  • “by Preferential Segregation of Oxide on Edges and Vertices” 说明了实现目标所采用的研究方法，也就是通过氧化物在边缘和顶点的优先偏析。
  • “Oxygen Reduction on Ti - Au@Pt/C” 指出了研究的对象，即对 Ti - Au@Pt/C 进行氧还原反应的研究。

对各选项的分析

  • A. Research method（研究方法）：从标题中的 “by Preferential Segregation of Oxide on Edges and Vertices” 可以明确推断出研究方法，所以该选项不符合题意。
  • B. Research goal（研究目标）：“Increasing Stability and Activity of Core - shell Catalysts” 清晰地体现了研究目标，因此该选项也不符合题意。
  • C. Research question（研究问题）：标题中并没有直接提出一个明确的研究问题，它更多地是阐述了研究的目标、方法和对象，所以该选项符合题意。
  • D. Research target（研究对象）：“Oxygen Reduction on Ti - Au@Pt/C” 表明了研究的对象，故该选项不符合题意。
