In this study, poplar‐catkin‐derived N, P co‐doped carbon microtube catalysts with highly active sites and a large accessible surface area exhibit desirable oxygen reduction reaction (ORR) activity in an alkaline solution and excellent applications in Zn‐air batteries (ZABs). In particular, the catalytic activity of the N, P co‐doped carbon microtubes toward the ORR is as good as that of benchmark Pt/C, albeit better in terms of tolerance and stability. Furthermore, a ZAB fabricated using the as‐developed catalyst exhibits a specific capacity of 649 mAh gZn−1 and a peak power density of 125 mW cm−2; these values are comparable to those of Pt/C catalysts (644 mAh gZn−1 and 130 mW cm−2, respectively), indicative of the promising applications for sustainable energy storage. In addition, an alkaline water‐splitting cell powered by this assembled ZAB can generate H2 gas in a stable manner under ambient conditions. The successful conversion of considerable catkin sources to high‐value carbon materials will provide insights into the future development of other high‐performance electrocatalysts from abundant “green” bio‐waste.

Problem statement:This study applied the Food-Related Lifestyle (FRL) instrument for market segmentation in the Taiwan food sector. FRL instrument was originally developed by the Market-Based Product and Process Development in Danish (MAPP) research group, the instrument was adjusted for the Chinese food culture. The FRL instrument is wildly applied to empirical market analysis, especially in European nations. Its reliability and validity are also empirically proven. The present study serves as the first attempt to employ the FRL instrument to explore food-related lifestyle segments in Taiwan. Approach: A short questionnaire was issued to 650 Taiwanese consumers using quota sampling procedures and 565 valid responses were collected. Using the two-step cluster analysis, four distinct food-related consumer lifestyle segments were identified. Results: The four segments includes: traditional consumers (23.54%), adventurous consumers (27.61%), uninvolved consumers (24.07%) and astute consumers (24.78%). Conclusion/Recommendations: Comparison showed that these segments differ in their attitudes and behaviors towards food consumption. Profiles of the segments are achieved by observing the socio-demographic characteristics of typical segment members.
